The objective of this research is the development of an effective design of an assembly line for heaters production by taking into consideration work measurement, line balancing and ergonomic problems. As the assembly line is still not in existence and no data are available, it is quite difficult to evaluate, for each assembly line workstation, the work assignment, the assembly times as well as...

The line-cell (or line-seru) conversion is an innovation of assembly system applied widely in the electronics industry. Its essence is tearing out an assembly line and adopting a mini-assembly unit, called seru (or Japanese style assembly cell). In this paper, we develop a multi-objective optimization model to investigate two line-cell conversion performances: the total throughput time (TTPT) a...

objective: poverty alleviation is an essential step to achieve economic development. this is why identification exercise is so crucial. traditionally, different aspects of insecurities have not be taken into poverty measurement. many types of insecurities have adverse impacts on household welfare. identifying vulnerability of household can serve identification of the poor households. methodolog...

In this paper, a goal programming model for the simple U-line balancing (ULB) problem is developed. The model is based on the integer programming formulation developed by Urban [Urban, Note: Optimal balancing of U-shaped assembly lines, Management Science 44(5) (1998) 738–741] for the ULB problem and the goal model of Deckro and Rangachari [Deckro, Rangachari, A goal approach to assembly line b...

The self-assembly of the protein shell ("capsid") of a virus appears to obey the law of mass action (LMA) despite the fact that viral assembly is a nonequilibrium process. In this paper we examine a model for capsid assembly, the "assembly line model," that can be analyzed analytically. We show that, in this model, efficient viral assembly from a supersaturated solution is characterized by a sh...

A “bucket brigade” assembly line is capable of complex new dynamics if workers differ in the speeds at which they walk back to get more work. In this extended model the line is self-balancing if each worker takes work from a colleague who is more slowed by the act of work than he. Under alternative schemes of sharing work the behavior of an assembly line can be chaotic and so effectively indist...
