The purpose of this study is to first investigate the efficiency of the most commonly used performance measures for minimizing the number of workstations (NWs) in approaches addressing simple assembly line balancing problem (SALBP) for both straight and U-shaped line, and second to provide a comparative evaluation of 20 constructive heuristics to find solutions to the SALBP-1.
A total of 200 problems are solved by 20 different constructive heuristics for both straight and U-shaped assembly line. Moreover, several comparisons have been made to evaluate the performance of constructive heuristics.
Minimizing the smoothness index is not necessarily equivalent to minimizing the NWs; therefore, it should not be used as the fitness function in approaches addressing the SALBP-1. Line efficiency and the idle time are indeed reliable performance measures for minimizing the NWs. The most promising heuristics for straight and U-shaped line configurations for SALBP-1 are also ranked and introduced.
Results are expected to help scholars and industrial practitioners to better design effective solution methods for having the most balanced assembly line. This study will further help with choosing the most proper heuristic with regard to the problem specifications and line configuration.
There is limited research assessing the efficiency of the common objectives for SALBP-1. This study is among the first to prove that minimizing the workload smoothness is not equivalent to minimizing the NWs in SALBP-1 studies. This work is also one of the first attempts for evaluating the constructive heuristics for both straight and U-shaped line configurations.
Introduction Consider a hi‐fi loudspeaker manufacturing company acquired on the brink of insolvency by an American multinational. The new owners discover with growing concern that the product range is obsolete, that manufacturing facilities are totally inadequate and that there is a complete absence of any real management substance or structure. They decide on the need to relocate urgently so as to provide continuity of supply at the very high — a market about to shrink at a rate unprecedented in its history.
A Study in Organisation. Under the non‐committal title “Construction of Esso Refinery, Fawley; A Study in Organisation”, A. P. Gray and Mark Abrams tell the story of how this vast £37½ million venture was constructed in little more than two years—thanks to outstandingly efficient management both at the planning and construction stages.

A study of the price discounts granted by Morton Salt Company and other producers of table salt in the U.S. on their sales of table salt to grocery wholesalers and retailers. The discounts were found to be illegal under the Robinson-Patman Act by the Federal Trade Commission and the Supreme Court. The Commission and the Court believed that the discounts were unjustified price concessions granted to “large” buyers, consistent with the concerns of the Robinson-Patman Act. However, the evidence indicates that the most common discount – the “carload discount” – was received by virtually all buyers, regardless of the buyer’s size; the other discounts – “annual volume” discounts – though received primarily by “large” buyers, were likely cost based. The history of the discounts and likely reasons why they were granted are explored in detail.

Properly conceived, conducted and interpreted, motivation research can be an extremely powerful management tool, designed to help the manufacturer or advertiser to sell more goods. Its aim is to expose the market situation, explain it and suggest courses of action which will lead to desired changes. It is a way of looking at a problem rather than a collection of specialist techniques and is strictly practical. Hence it can be used alongside other market research tools for the solution of marketing problems and can be applied to a wide range of business activities. Much of its development has been in the advertising field but it can also help in the formulation of production policy, solving packaging problems and marketing operations. It is examined here in all these contexts. The idea of motivation research, the reasons for its use and the techniques by which to apply it are discussed, as well as the pitfalls that are likely to occur. New and imaginary case studies are used throughout to illustrate points. A review of the subject literature is included.

Cycle time fluctuations in assembly lines are one of the important reasons of re‐balancing. As a result of re‐balancing of assembly lines, it will be necessary to change task sequences or equipment locations. The purpose of this paper is to find the task sequence which enables assembly line balancing (ALB) with minimum number of stations (NS) for different cycle times such that tasks and equipment or fixture locations remain unchanged.
In this paper a heuristic which consist of two stages is proposed to find a common task sequence for different cycle times in assembly lines.
It is shown that optimal NS for different cycle times can be achieved with a fixed task sequence.
The approach is limited to a single model case. Model variety together with cycle time variety can be investigated in further studies.
Assembly lines which require less time and cost for re‐balancing can be easily designed by the proposed approach.
ALB problem is handled with a new viewpoint. Also, it is observed that the proposed approach serves as a bridge between assembly line design and balancing. In this regard, it is thought to have an important place in the ALB literature.
