Abstract:

Successful Army operations depend on the efficient handling, storage, and flow of materials. Accidents associated with materiel handling activities not only affect the efficiency of an operation but also endanger the lives of Army personnel. In addition, the annual cost to the Army for materiel handling accidents averages approximately $4,315,836. The high incidence and cost of materiel handling accidents poses significant operational problems for the Army. The Army could make great strides in alleviating these operational burdens as well as meeting its safety goals through concerted accident prevention efforts. The U.S. Army Safety Center is making its first attempt to quantify the system problems in the Materiel Handling Major Problem Areas. Improvements in the design of materiel handling equipment and in supervisory practices and training methods may be applicable both to other government agencies and in the private sector.

Abstract:

In line with the quality management principles applied within a functional settlement of an organization, unconcerned of the size or principal object of activity, port operators should be treated as operational entities carrying out specific activities, aiming to achieve specific objectives, that are prior determined but in dependence with their location and role determined alongside the port logistic chain. The process-based approach involves establishing the processes and sub-processes applied to achieve the port operator's entire set of objectives, functions and tasks. As with any business, the company aims at lowering costs, delivering better, consistent and predictable results, focusing on priority. These can be more easily achieved through a process approach that allows the systematic definition of the activities necessary to achieve the desired outcome, setting clear and quantifiable responsibilities for key management activities, analysing and measuring the capability of core activities, identifying links between key activities and the organization's functions, focusing on the elements that can improve the organization's activities (resources, methods and materials) and assessing the risks, consequences and impact of activities on all stakeholders. Carrying out the process map, identifying the data stream, establishing input and output data are the first steps applied in orderto achieve a process model that will further allow the identification of indicators to improve the quality of the services provided and consequently to ensure the satisfaction of customers and other stakeholders.

Abstract:

Ground handling operations can be accepted as the heart of safe flight, beginning from the ground to the air. In ground handling activities where there is tight time pressure, human resources are of great importance in efficient and safe service. This study presents ergonomic risk factors affecting the operational and corporate performance of aircraft ground handling services. Ergonomic related performance fields are identified via expert opinion and a taxonomy focusing on classified error conditions for ground handling services. The taxonomy is developed to improve corporate performance while eliminating ergonomic risks and maintaining a safe working environment. Identified performance risks are intended to be a guide for operational managers in aircraft ground operations in the field of investments, decision making and safe operations.

Abstract:

Ground handling services constitute an important element of airline operations and significantly affect traffic stability and punctuality. In this article, the existing and potential impact of airline handling on air traffic volatility is reviewed from the point of view of airlines and ground operations. The issues of airline expectations towards ground handling agents (including handling rates, turnaround time, passenger services, and ramp services) are explored. In addition, the impact of an airline’s schedule and the volatility of its operations on the performance and operational requirements of handling agents is discussed, including actions required by handling agents in response to the above challenges. The mechanism of how the volatility of an airline’s schedule and its operations may impact the volatility of ground operations (directly and indirectly) is considered. The statistics of airline delays caused by ground operations are presented and discussed. The issue of the correctness of air traffic delays reporting by airlines is investigated.Furthermore, this article investigates internal factors of ground handling agents and their impact on air traffic volatility. The existing and potential considerations discussed include staff management issues (in particular, employee rotation resulting in staff shortages and service quality, including punctuality), resources management, the ground service support equipment (including new developments aiming at limiting ground safety incidents), and their impact on performance.

Abstract:

This paper proposes a new optimization model for ship’s cargo handling operations which solution gives the structure of cargo handling resources required, along with attaining the minimum total ‘in-port’ costs and the minimum of time required for completion of cargo operations. Due to complexity of the model which consists of composite multi-objective functions together with several decision variables and constraints, the solution has been sought by utilization of an adapted genetic algorithm combined with a hybrid algorithm. Testing of the model on real world data yielded acceptable results in a short time. In the course of decision making, the ship’s operator can, on the basis of the proposed model and taking into consideration shipping market data, choose appropriate variation of the returned solution, which incorporates minimum costs, minimum of operational time and related cargo handling resources.

Abstract:

This article studies an operational problem arising at a container terminal. Klaipeda city port operations were surveilled up close and relevant remarks were made. The time efficiency of the existing container-lowering procedures using the simulation studies with a test-bed and with a real life crane operation was examined. Statistical analysis of the experimental results has showed that non-automated processes have higher time variance for the lowering process. The operations of quay crane for container handling “ship-to-shore” were analyzed, and lowering procedures time variations were determined. Each container is transported at operators own risk and with pre-defined time efficiency; therefore, it is hard to predict the optimal time for each container handling operation, thus, eventually, additional costs arise. Mathematical model was developed, which described dynamical characteristics of the container movement during lowering procedures. The lowering crane operation was modeled using known dynamic values for each separate case, and the complexity of the problem was proven. The results of modeling and experimental results show that it is possible to achieve optimal values with the existing processes.

Abstract:

Container ships transport a large number of valuable cargoes, and there is a demand for less expensive and faster transportation options. Weather, vessel type, and the nature and amount of the goods are all external elements that might impact container handling times, which are directly related to overall port stay time. In this scope, container terminal operations could be optimised with the help of historical data which provides access to classification and prediction of the cargo handling operations. In this study, the real-time data of a container terminal operation is analysed with different machine learning techniques along with the Fuzzy C-Means clustering method. The results show that Fuzzy C-Means clustering has a positive impact on the explanatory power of models in container terminal operations. The research revealed that an increase in wind speed influences cargo handling time for mobile cranes.

Abstract:

The rail–water coordinated operation area in a container terminal is the key place to operate the transshipment of intermodal containers between the rail and the sea—the handling efficiency in which can affect the overall transport turnover efficiency. A complicated operational process for various handling equipment exists in this coordinated operation area and can lead to a large amount of energy consumption and environmental pollution. This study proposes an integrated optimization approach to manage the multiple equipment integrated scheduling and storage space allocation problem in an energy-efficient way. A bi-objective optimization model is proposed to minimize the overall operation time and energy consumption, in which the handling operations of imported and exported intermodal containers are considered simultaneously. A genetic algorithm based heuristic algorithm is developed to solve the problem. Results from computational experiments indicate the feasibility and effectiveness of the proposed model and algorithm, verifying that a near-optimum solution can be obtained for large-scale problems efficiently, which contributes to the improvement of operation services in rail–water intermodal container terminals.

Abstract:

Digital transformation is becoming an inevitable trend, having a profound impact on business activities, processes,, and modelsands improving the operational efficiency of businesses. In enterprises, especially small and medium-sized enterprises, accounting professions are mainly still handled manually on books and documents. They have not standardized the professions, especially those that arise in the course of operation. This makes it difficult for accounting such as accounting work gradually increases, the handling of work is delayed, easily confused and errors .... Leading to limiting the development and expanding the size of the business. The problem for each business is the need to automate some accounting operations to adapt to the trend and context of digital transformation, contributing to improving the competitive efficiency of the business. Stemming from the above difficulties, the research will find solutions to help businesses approach and apply processing operations professionally towards the formation of digital businesses. The article will focus on building cash accounting modules and handling professional accounting processes to implement digital transformation in enterprises. The operations mentioned in the article include building the professional process of cash accounting, controlling cash collection - spending, the process of digitizing documents stored at the enterprise, etc... The article will propose how to process data and make reports required by managers for decision-making based on invoices and handling arising transactions.

Abstract:

AbstractThe traditional distinction between military and law enforcement operations is increasingly difficult to uphold. This gives rise to a number of difficult and complicated challenges in regard to the handling of detainees. Legal ambiguity may lead to operational uncertainty, which may hamper the efficiency of a given United Nations (UN)-mandated international military operation. It is in the interest of no one, not least the detained individual. The author argues that the Copenhagen Process on the Handling of Detainees in UN-mandated international military operations is a necessity to ensure the full protection of any individual detained during an UN-mandated international military operation and thereby ensuring the efficiency of the efforts of the international community to bring stability and peace to States and regions in dire need. On the key legal question concerning the relationship between international humanitarian law and human rights law, it is necessary to conduct a thorough analysis of the relevant provisions of both bodies of international law in context. When this is done, most of the claimedincongruities between the two bodies of law disappear – and thereby also the basis for the sometime heateddiscussions between the advocates of one or the other body of law.

Abstract:

We synergistically apply queueing theory, integer programming, and stochastic simulation to determine an optimal staffing policy for a repair call handling center. A stationary Markovian queueing model is employed to determine minimal staffing levels for a sequence of time intervals with varying call volumes and mean handling times. These staffing requirements populate an integer program model for determining the mix of call agent shifts that will achieve service quality standards at minimum cost. Since the analytical modeling requires simplifying assumptions, expected performance of the optimal staffing policy is evaluated using stochastic simulation. Computational efficiency of the simulation is improved dramatically by employing the queueing model to generate an analytic control variate.

Abstract:

The Pig is an important tool during the process of oil-gas pipeline’s production, replacement, daily operation and management. Its outer diameter is 2% to 5% larger than the inner diameter of pipelines. It stays a clamping state in the pipelines. The fluid pressure difference before and after the Pig push it from the beginning to the end of the pipelines in order to clear all kinds of impurities in the pipelines and detect the internal and external wall corrosion status of the pipelines or achieve other goals. But during the cleaning-up operation, it is difficult for the Pig to get in and out of the pipelines because of its heavy weight. So a Pig and Pigging ball handling trolley is designed in this paper to push and pull the Pig or Pigging ball to get in and out of the Pig launcher & receiver device. This handling trolley will mechanize the Pigging operations, reduce the labor intensity and improve the work efficiency.

Abstract:

Robotic handling systems are increasingly applied in distribution centers. They require little space, provide flexibility in managing varying demand requirements, and are able to work 24/7. This makes them particularly fit for e-commerce operations. This paper reviews new categories of automated and robotic handling systems, such as shuttle-based storage and retrieval systems, shuttle-based compact storage systems, and robotic mobile fulfillment systems. For each system, we categorize the literature in three groups: system analysis, design optimization, and operations planning and control. Our focus is to identify the research issue and operations research modeling methodology adopted to analyze the problem. We find that many new robotic systems and applications have hardly been studied in academic literature, despite their increasing use in practice. Because of unique system features (such as autonomous control, flexible layout, networked and dynamic operation), new models and methods are needed to address the design and operational control challenges for such systems, in particular, for the integration of subsystems. Integrated robotic warehouse systems will form the next category of warehouses. All vital warehouse design, planning, and control logic, such as methods to design layout, storage and order-picking system selection, storage slotting, order batching, picker routing, and picker to order assignment, will have to be revisited for new robotized warehouses.

Abstract:

In real life situations, the material handling strategy of on-site storage systems is usually determined during the design of the storage system, which is no longer reviewed later. The strategy is typically determined by the person(s) designing the storage system, without the use of scientific methods, based on previous experience. Without a thorough periodic review of operational strategy, most companies’ warehousing systems have significant logistical losses (e.g., unnecessary material handling, waiting, operations), which also negatively affects the sustainability of the logistics operations. Therefore, eliminating these losses can increase both the competitiveness and the sustainability of companies. For this reason, the aim of this publication is to introduce a gap-filling test method that allows the selection of an optimal material handling strategy covering the total value stream in a demand-driven storage environment, using the opportunities offered by the Industry 4.0 concept, in particular in the field of big data analysis. This integrated approach has so far not emerged in the study of warehouse material handling strategies. Beyond the obvious economic benefits, the application of this method can clearly help companies to achieve a higher level of sustainability in their logistics operations, as it allows storage systems to operate more efficiently while minimizing material handling losses, ultimately resulting in a lesser demand for energy and raw materials. Moreover, this can also result in a reduction in the human and machine resources required to perform the tasks.

Abstract:

SUMMARYIn this paper, an adaptive learning (A-L) control scheme is proposed for cooperation of two manipulators handling a rigid object with model uncertainties. For robots performing repetitive cooperating tasks, their operations are decomposed into two modes: the single operational mode and the repetitive operational mode on which the A-L controller is based. In the single operational mode, the controller is a learning based adaptive controller in which the robotic parameters are updated by using the information of the previous operation. In the repetitive operational mode, the controller is a model-based iterative learning controller. The advantages of the A-L controller lie in the fact that it can improve the transient performance as robots repeat operations at a high speed of the learning convergence. Simulation results ascertain that the A-L algorithm is effective in controlling two cooperated robots with model uncertainties.

A gondola with a body of solid type – an eco-nomically effective unit of a rollingstock. Most of the damages of gondola bodies is caused at handling operations with the failure of requirements observance established. In the paper the assessment of deflected mode body in the body at the lump load drop with the mass of 500 kg is carried out. Normal stresses and travels arising at the blow of load in the sections of joints of frame beams between each other, side and end walls are analyzed. The values of stresses three times higher than the foreseen ones with “Standards…” are adopted as reference valuations. It is substantiated by test results and the comparison of material characteristics at deadweight and dynamic loads. As a result of car body multichoice computations on basis of the detailed MCE there was established the following: the closer the place of a lump blow to a supporting longitudinal to the car body end is, the stresses are higher in it. Stresses arising in the supporting longitudinal situated between an end girder and a body bolster beam reach 998 H/mm, at the same time in the middle of the car body of a gondola they do not exceed 450 H⁄mm². If a load lump falls down on the joint of cross-beams and longitudinal ones, then stresses in their sections 10-15 times less, than if the fall were to a strengthening beam. In the main the maximum stress distribution is limited by small areas located between two neighboring crossbeams. The research results have shown, it is necessary that additional bearing elements absorbing a blow should be introduced in a frame.

Abstract:

The article is devoted to modelling the duration of cargo operations at intermediate stations on the route of a modular express freight container train (MEFCT), that is, a train with a fixed schedule heading from the initial to the final station without remarshalling a rolling-stock, but performing the cargo handling operations for loading/unloading of containers at intermediate stops on the route. Cargo handling operations at intermediate stations of a MEFCT entail a non-productive run of a loader along the train from one container to be reloaded to the other. In the case of a random placement of containers on a train, the completion time of the complex of cargo handling operations will be a random variable. Modelling of this random variable is carried out on the basis of the Monte-Carlo method in order to determine the most probable time of stopping of a train to perform cargo handling operations, as well as possible deviations from the average value. At the same time, duration of the complex of cargo handling operations at the station is proposed to be estimated depending on the volume of loading/unloading operations of containers at each point and the distance travelled by a loader along a train, which is given in the model by a random evenly distributed value. Based on numerical experiments with the model, the regression dependence of the time of cargo handling operations on the volume of container loading was established, as well as variations of this value due to the random nature of the placement of containers on a train. The model allows you to form a reasonable timetable for a MEFCT and increase the reliability of departure time of a train.

Abstract:

It is a global trend for the airport ground handling market to become liberalised. Fiercer competition lead to the necessity to improve efficiency and minimise costs. A mathematical model of optimal resource allocation by aircraft ground handling company using duality theory has been suggested. The numerical results for the solution of the task under the question which were obtained with the relevant software package, proved validity of the specified theoretical preconditions and allowed to improve the work schedule of the experimental aircraft ground handling company in accordance with a specified efficiency criterion.

Abstract:

There is a limited understanding of automation in construction materials-handling processes utilised by manufacturing firms in Nigeria. This article evaluates the level of utilisation of automation in construction materials-handling operations by manufacturing firms in North-Central Nigeria, to improve operational efficiency and reduce operating costs. Using a case study research design, quantitative data (observation guide with measurements) were collected from 32 purposively selected construction-material manufacturers. A total of 72 customers’ orders were observed and recorded to be representative of deliveries from the sampled (n=32) manufacturers’ warehouses to other terminals. The descriptive method of data analysis was employed using percentages and results presented in a form of bar charts. The study reveals low-level utilisation of automation in the combined processes of order picking, storage, loading, and offloading of material. These imply increasing material costs and causing a delay in delivery. The article concludes by providing construction-material manufacturers with areas that require automation to optimise material-handling operations. A recommendation is made for further study to explore why automation is not utilised despite its advantage.

Abstract:

The central Monte-Carlo production of the CMS experiment utilizes the WLCG infrastructure and manages daily thousands of tasks, each up to thousands of jobs. The distributed computing system is bound to sustain a certain rate of failures of various types, which are currently handled by computing operators a posteriori. Within the context of computing operations, and operation intelligence, we propose a Machine Learning technique to learn from the operators with a view to reduce the operational workload and delays. This work is in continuation of CMS work on operation intelligence to try and reach accurate predictions with Machine Learning. We present an approach to consider the log files of the workflows as regular text to leverage modern techniques from Natural Language Processing (NLP). In general, log files contain a substantial amount of text that is not human language. Therefore, different log parsing approaches are studied in order to map the log files’ words to high dimensional vectors. These vectors are then exploited as feature space to train a model that predicts the action that the operator has to take. This approach has the advantage that the information of the log files is extracted automatically and the format of the logs can be arbitrary. In this work the performance of the log file analysis with NLP is presented and compared to previous approaches.

Abstract:

AbstractThe Royal Marines Band Service (RMBS) deploys in support of the Royal Naval Medical Service in a variety of operational roles. This article describes the roles that RMBS personnel performed whilst deployed on board RFA ARGUS during the recent Operation GRITROCK. The article is divided into five main sections, each describing one aspect of the work that RMBS ranks were asked to undertake: casualty handling; working within Primary Casualty Receiving Facility (PCRF) departments; personal protective equipment (PPE) monitoring and drills; temperature monitoring; and last, but not least, musical support. This will provide the reader with an insight into what the RMBS have achieved whilst deployed on board ARGUS and also what skills they are able to bring, both to contingency operations and operations in the medical environment.
