    Although several researchers have studied the problem of optimizing buffer allocation to maximize the efficiency of a reliable production line, there is no method that can handle this problem for large production lines, in a computationally efficient way (see for example,, and). These methods are based on comprehensive studies to characterize. The allocation of servers and the allocation of work are two important decision variables in designing production line systems. Previous studies of each variable in isolation have found that throughput is maximized by using an allocation that gives preferential treatment to interior stations (especially center stations) over the two end by:

Improving working conditions and productivity in this industry could thus result in making these small and medium-sized enterprises more competitive, efficient and safer, and also extend better protection to women workers. This publication follows a similar approach to the manuals on Higher productivity and a better.

Book Description. This book covers the area of unpaced, unbalanced production lines. You will find an up-to-date discussion of how designing these lines can be made more efficient by taking advantage of inherent imbalance -- for example operators who work at different speeds- a concept which has traditionally been seen as an obstacle to efficient production.

This paper provides results related to the optimal design of unpaced production lines. It has been shown previously that unbalancing an unpaced production line in an appropriate way will increase its production rate.

Results are presented here which show how the optimal allocation of work between stations changes with respect to —Cited by: Request PDF | Unpaced production lines with three simultaneous imbalance sources | Purpose – The purpose of this paper is to investigate the performance of unpaced reliable production lines.

Two key decisions in designing an unpaced assembly line are the allocation of work to the stations and the allocation of buffer storage space between the stations.

The failure and repair rates (based on) are summarized in Table efficiency in terms of MTBF was fixed at % for three levels of reliability. For example, the line efficiency for high reliability is MTBF 25/(MTBF 25 + MTTR 5 = %).

Abstract: We compare the efficiency of reliable and unreliable unpaced production lines that are unbalanced in terms of their buffer storage capacities to a corresponding line with equal sized buffers.

The lines were simulated with different values of line length, buffer storage size, mean buffer capacity, and configuration of buffer : Sabry Shaaban, Tom McNamara, Sarah Hudson. As illustrated in the table, unpaced synchronous production lines tend to be more efficient than paced lines, particularly with high task variance.

Line balancing can be used to design efficient manufacturing systems for paced assembly lines when the operation times are known, but may provide inefficient assignments with variable task times.

Thus, we propose the use of unpaced synchronous lines.

Toward characterizing the optimal allocation of work in production line systems with variable operation times.

In modern production systems that perform under high cost environments, even small improvements in line efficiency represents large savings over the lifetime of an assembly line.

In the beginning of modern production systems, it was thought that a `perfectly balanced' line was the most efficient way to design the line. However in practice, the ideal perfectly balanced line Cited by: 4. In this chapter, two separate design problems are considered, viz., the work-load allocation problem and the server allocation problem in production lines.
