A Kanban Production System is designed to help a factory line meet fluctuating demands for multiple part types. Based on the parameter settings of the Control-Point Policy, the optimum Kanban levels are obtained. The simulation software Simul8 was used to model the factory line and the Kanban system. Using the optimum Kanban levels, the Kanban system will act as an automatic production scheduling system that will indicate clearly when and how much of each part-type should be produced. Use of this system will avoid unnecessary inventory and changeover cost incurred by the existing Kanban system used by the factory line.

Повний текст джерелаGlobaliseringen och den ökande pressen på företag att producera och få ut produkter på marknaden på kortast möjliga tid har lett till att det ställs allt högre krav på produktionssystemen. Allför ofta leder kortsiktigt tänkande och jakten på vinster till att företag väljer enkla och billiga snabblösningar. Tillverkningsindustrin förändras långsamt medans marknaden ändras fort, vilket kräver att företagen kan planera för långsiktiga kapacitetsökningar och ändå ha beredskap för att snabbt kunna anpassa sig till förändringar. Det som till allra största del avgör hur effektivt man kan producera och leverera en produkt till marknaden är vilket produktionssystem ett företag använder samt en välformulerad tillverkningsstrategi. Vilket produktionssystem man väljer är beroende av vilka förutsättningar och krav ett företag har lika mycket som av marknadskraven. Man måste ta hänsyn till det nuvarande produktionssystemets prestanda och möjlighet att hantera ändrade produktionsvolymer och variantflora och utvärdera detta ur en ekonomisk synvinkel. Under detta examensarbete har för- och nackdelar med batchflöde och enstycksflöde undersökts och utvärderats. Generellt sätt har enstycksflöde konstaterats vara mest effektivt rent ekonomiskt och prestandamässigt. Däremot, har batchflöde tilldelats fördelar som hög flexibilitet att hantera olika produktvarianter och bättre möjligheter att styra materialflödet jämfört med enstycksflöde. Det har även undersökts vilka som är de mest avgörande faktorerna som styr valet av enstycksflöde eller batchflöde. Under arbetets gång framkom det att den mest avgörande faktorn som påverkar valet av produktionssystem var företagets Produktionsstrategi. Den kan anses vara grunden för alla beslut rörande produktionssystemet och framtida satsningar. Där visar man var företaget befinner sig idag samt var man vill vara i framtiden och vilka beslut man måste ta för att ta sig dit. Den ekonomiska faktorn är minst lika viktig, då alla beslut i slutändan handlar om mer eller mindre kostsamma investeringar. Samtidigt måste det valda produktionssystemet vara så effektivt som möjligt och generera pengar till företaget. Med utgångspunkt från dessa två huvudfaktorer har andra intressanta faktorer tagits fram, som inte påverkar valet av produktionssystem i lika hög grad, men som ändå kan anses vara viktiga i sammanhanget. Forskningsarbetet har bedrivits under 20 veckors tid, där datainsamling har utförts via fallstudier på fyra företag som tillverkar liknande komponenter inom fordonsindustrin. Vidare datainsamling har gjorts genom en litteraturstudie där relevant material för forskningsfrågorna har undersökts. Detta har lett till en samlad kunskapsbas gällande för- och nackdelar med de respektive produktionssystemen samt bakomliggande orsaker till att välja något av dessa produktionssystem. Utifrån det samlade materialet från fallstudierna samt de teoretiska rönen har sedan en tankekarta tagits fram, som visualiserar de avgörande faktorerna som påverkar valet av ett produktionssystem. Denna tankekarta kan företag använda sig av för att på ett strukturerat sätt utvärdera nuvarande produktionssystemet samt planera för framtida förändringar inom produktionen.

This paper studies the admission control method for different manufacturing system with process queue time constraints. In semiconductor, Thin Film Transistor-Liquid Crystal Display (TFT-LCD), other industries, the waiting time of WIP is limited to upper bound in system, the time constraint is called the process queue time constraint (PQT). When the PQT constraint is violated, a significant scrap cost will be accrued. The queue time constraint makes the production control difficult, production managers need to balance the need for achieving production targets and yield quality. To raise the productivity, batch process machine is widely applied in manufacturing system. The batch machine can process several jobs to reduce waiting time and improve system throughput rate, the increased productivity will facilitate industries to gain more revenue. To fulfill the variety customer demand, multiple product machine is also broadly used in manufacturing system. The multiple product machine can process different type of jobs to meet customers’ diversified demand, the overall revenue will be increased. Hence, this research focuses the batch process manufacturing system and multiple product manufacturing system. Under the PQT problem, we develop the optimal production control method for the manufacturing systems aforementioned. We use Markov decision processes (MDP) to formulate a batch process admission control (BPAC) model in batch process manufacturing system under PQT constraint. Moreover, we also propose a dynamic admission selection control (DASC) model in multiple product manufacturing system under PQT constraint. The objectives of our policies are to minimize the sum of inventory holding costs and scrap costs. We also conduct simulation study to verify the robustness of our method. The simulation results reveal that our policies significantly reduce total costs while improving throughput and system utilization.

Повний текст джерелаFormal Theories (FTs) have proved their utility in “traditional” engineering areas. They permit analytical derivation of the specified system’s performance even before the system’s actual physical implementation. This is of great help giving the system’s designer and user to critical insight into the system being implemented, but before actually investing resources. However, concerning the “state-of-the-art” of the development of a FT of production systems (PS) or Virtual Enterprise (VE), we are not aware of any consistent and rigorous approach in this direction, except the initial results managed in the Centre of Production and Systems Engineering at the University of Minho. It is commonly perceived that the FTs are difficult to understand (from the cognitive point of view), difficult to learn, and therefore, difficult to develop. In terms of complexity theory, the formal theory development process is considered as a highly complex problem. Also, it is difficult to cover all the user requirements while developing a FT. On the other hand, the lack of a Formal Theory of production systems and VE is a serious obstacle to effective and efficient development, and application, especially of advanced and emerging production systems and VE concepts. In the modern times, these are the great drivers of economy and encourage innovation as well as entrepreneurship. A FT also permits an analytical synthesis, i.e. design, of the system through formal methods. This guarantees the fulfilment of the system design objectives. These are the motivational factors behind the presented thesis. The principal objective of the presented thesis is the validation of the scientific thesis concerning the problem of automatic synthesis and use of FT of production systems and VE. For the automatic synthesis of FT, the inductive inference approach is selected because of its ability to “learn” effectively from a set of examples (comparable to real-life case studies or hypothetical/abstract models for the purpose of learning). The Formal Theories are modelled through Formal Grammar and thus the problem of automatic synthesis of FT is actually reduced to the problem of Grammatical Inference. There are several methods for Grammatical Inference for different classes of formal grammars. For the presented work, the Context-free class of grammar was selected to model the intended formal theories of production systems and virtual enterprises. Through a machine learning algorithm, the formal theories were “learned” and these learned (synthesised) formal theories could generate other more complex architectures than the ones used for learning. Several experiments were carried out and a quantitative as well as qualitative analysis was carried out. The analysis of experiments’ results showed that the approach proved to be effective and with potential for real-life applications for synthesis of formal theories for virtual enterprise and similar architectures.
As Teorias Formais (TFs) têm provado a sua utilidade nas áreas de engenharias tradicionais. Elas permitem uma análise derivativa do desempenho de um sistema específico mesmo antes da sua implementação física. Isto é de grande ajuda, oferecendo ao criador e utilizador do sistema uma visão crítica sobre o sistema a ser implementado, antes de investir em recursos. No entanto, e no que diz respeito ao estado da arte do desenvolvimento da TF de sistemas de produção (SP) ou Empresa Virtual (EV), não se está consciente de qualquer abordagem consistente e rigorosa nesta direção, com exceção aos resultados obtidos pelo Centro de Engenharia de Sistemas de Produção da Universidade do Minho. Regra geral, TFs são difíceis de compreender (do ponto de vista cognitivo), difíceis de aprender e, por isso, difíceis de desenvolver. No âmbito da teoria da complexidade, o processo de desenvolvimento da teoria formal é considerado um problema de elevada complexidade, bem como de difícil satisfação de todas as necessidades dos utilizadores. Por outro lado, a ausência da Teoria Formal de SP e de EV é um obstáculo para o desenvolvimento e aplicação eficaz e eficiente, especialmente para os conceitos de SP avançados e emergentes e de EV. Nos tempos que correm, estes são os grandes motores da economia e inovação, bem como o empreendedorismo. A TF permite também uma síntese analítica, isto é o design do sistema a partir de métodos formais, garantindo que os objetivos deste sejam alcançados. Estes são os fatores motivacionais por detrás da presente tese. O principal objetivo é a validação da tese científica relativo ao problema da síntese automática e uso de TF de SP e EV. A abordagem da inferência indutiva é selecionada, para a síntese automática da TF, devido à sua capacidade de “aprender” efetivamente a partir de um conjunto de exemplos (comparável com casos de estudos da vida real ou modelos hipotéticos/abstratos para o propósito da aprendizagem). As TFs são modeladas através de Gramática Formal e, por isso, o problema da síntese automática da TF é reduzido atualmente ao problema da Inferência de Gramática, para a qual existem vários métodos para diferentes classes de gramaticas formais. Para o presente trabalho, a classe de gramática livre de contexto foi selecionada para modelar as teorias formais pretendidas de SP e EV. A partir de um algoritmo de “machine learning”, as teorias formais são “aprendidas” e estas teorias formais aprendidas (sintetizadas) podem gerar outras arquiteturas mais complexas do que as que foram usadas para aprender. Várias experiências foram levadas a cabo, bem como uma análise quantitativa e qualitativa. A análise dos resultados das experiências mostraram que a abordagem provou ser eficaz e com potencial para aplicações na vida real, para a síntese de TFs para EV e arquiteturas similares.

The government has strongly promoted the concept of Industry 4.0 in recent years. Many industries have begun to transform and move toward the goal of unmanned factories. A great deal of efforts had paid to replace traditional manpower with robotic arms or automated machines on production line. However, enterprises are focusing on technical computer applications. The development of testing of consumer electronics parts is less concerned in the automated innovation. Especially in the production of consumer electronics control panels, fully automated functional testing is still difficult to achieve. Many small to medium sized enterprises are developing small-volume production of a wide range of different items. The functions of each product are different. It is necessary to manually check whether the function is normal or not, and it takes too much labor cost. On the other hand, a fully automated testing approach requires a large number of different functional test equipment. It will cost too much for the cooperative. This thesis mainly focuses on the design of a scalable automatic detection system at low cost to reduce the cost of transformation in production test, to speed up the test process, to lower personnel cost, and to record abnormal data for analysis to improve production yield. This study uses Microchip’s PIC16F1947 controller chip to implement the experimental board, uses C language to write control function program at PC-end. On the main board, there are pre-designed simulated analog temperature output, power communication module, transistor communication module, AC/DC power detection module, stepper/ DC motor control verification module, short circuit detection module, DC 0-10V input detection, DC 12V output, and so on, covering features of most air conditioning, freezing/ cold storage control boards. It reserves multiple sets of SPI communication interfaces for subsequent expansion. To provide subsequent expansion of stable power supply, the design is to supply power by switching power. Java language is used to design PC-side human-machine interface for improved system portability. The main board has a record function for information such as production date, model and fault type. The related production information is exported into the database for analysis and improvement. To the data can be applied to the development product, the action logic is pre-designed. It has been found through experiments that automatic testing is very important. In addition to improving production speed and yield, it can improve the overall production line operation schedule effectively. On the other hand, transferring manpower away from the repetitive and troublesome working environment improves the productivity of employees. The overall working environment can be improved. At the same time, the company’s reputation can be strengthened due to the effective monitoring and improvement of product quality.

Повний текст джерелаProgramming tools are computer programs which help humans program computers. Tools come in all shapes and forms, from editors and compilers to debuggers and profilers. Each of these tools facilitates a core task in the programming workflow which consumes cognitive resources when performed manually. In this thesis, we explore several tools that facilitate the process of building intelligent systems, and which reduce the cognitive effort required to design, develop, test and deploy intelligent software systems. First, we introduce an integrated development environment (IDE) for programming Robot Operating System (ROS) applications, called Hatchery (Chapter 2). Second, we describe Kotlin∇, a language and type system for differentiable programming, an emerging paradigm in machine learning (Chapter 3). Third, we propose a new algorithm for automatically testing differentiable programs, drawing inspiration from techniques in adversarial and metamorphic testing (Chapter 4), and demonstrate its empirical efficiency in the regression setting. Fourth, we explore a container infrastructure based on Docker, which enables reproducible deployment of ROS applications on the Duckietown platform (Chapter 5). Finally, we reflect on the current state of programming tools for these applications and speculate what intelligent systems programming might look like in the future (Chapter 6).
