Today’s buyer markets and lean supply chains require build-to-order assembly systems with just-in-sequence (JIS) deliveries. Simultaneously production systems have become prone to supply disturbances (i.e. events) that endanger the synchronized delivery of all JIS components to the assembly line. To uphold production sequence stability, rescheduling is frequently required. Current methods, howe...

This paper describes our use of competitive analysis and the on-line model of computation in a product development setting; speciically, we use competitive analysis to evaluate on-line scheduling strategies for controlling a new generation of networked reprographic machines (combination printer-copier-fax machines servicing a network) currently being developed by companies such as Xerox Corpora...

Assembly line balancing has been a focus of interest to academics in operation management for the last decades. Despite diverse research works in this field, many problems still remained unsolved. Given the importance and attractiveness of the mixed product parallel lines balancing problem and the importance of the human factor in the development process and also very few studies in relation to...

In this paper we examine the various effects that workstations and repair loops with identical parallel processors and stochastic processing times have on the performance of a mixed-model assembly line. Of particular interest are issues related to sequence scrambling. In many production systems (especially those operating on just-in-time or in-line vehicle sequencing principles), the sequence o...

ABSTRACT: Parallel Assembly Lines with multi-line stations (PALBs) have been widely studied in recent years because PALBs can help improve the efficiency of a production system. However, need buffers has not considered PALBP literature. In this study, for first time literature, it is shown and demonstrated to consider use type line when their cycle times are different. Moreover, buffer sizing p...

Efficient use of capacity is significant to enable apparel businesses work cost-effectively and provide timely service their customers. The increase in assembly-line efficiency associated with lower operating costs. Therefore, the main purpose balancing assembly lines manufacture products as profitable quickly possible. In this study, we consider a single-model line problem workforce machine co...

In production systems of automobile manufacturers multi-variant products are assembled on paced mixed-model assembly lines, which have to be supplied by a lean in-house logistic with containers of different sizes, alternative supply policies and different number of parts. The assignment of operations to workplaces within the assembly line balancing problem and the assignment of containers to su...

Cholesterol plays a vital role in human body. Its unbalanced homeostasis, however, leads to health related problems. The elevated blood cholesterol levels are now considered a classic coronary risk factor and are suspected to lead to coronary artery diseases, causing 2.6 millions of deaths each year. Here, we develop a two-compartment mathematical model to investigate cholesterol transport in t...

Printed Circuit Boards (PCBs) are extensively used in diverse electronic products today. The placement process tends to be a bottleneck in a PCB assembly line, and many SMT PCB assembly researches focused on improving the process perspective of the machine operations. This research proposed a BPN data mining model to analyze the effect of a head calibration process on the defects of placement o...
