The quality of products and processes needs to be improved continuously in today's competitive environments. Unless these improvement efforts are focused properly, companies might not achieve desirable results in terms of sales, quality and productivity. Many quality improvement (QI) approaches have a limited evaluation of the factors involved in the selection of QI projects. Theory of constraints (TOC) has been proposed by some researchers as a remedy for the better selection of QI projects. However, these TOC-based approaches do not accurately capture ongoing product quality and its long-term effects on sales. Quality loss, on the other hand, can be used as a measure of customer dissatisfaction, which in turn determines the sales. The paper proposes an improvement of a TOC-based algorithm by incorporating quality loss with it. Using two simple manufacturing examples, it demonstrates that quality losses affect the product mix and QI project selection. It provides suggestions for further research directions for wider applicability of the proposed approach.

Due date and cost-based FMS loading, scheduling and tool management
Turkcan, Ayten; Akturk, M. Selim; Storer, Robert H. (Informa UK Limited, 2007-03-01)
In this study, we consider flexible manufacturing system loading, scheduling and tool management problems simultaneously. Our aim is to determine relevant tool management decisions, which are machining conditions selection and tool allocation, and to load and schedule parts on non-identical parallel CNC machines. The dual objectives are minimization of the manufacturing cost and total weighted tardiness. The manufacturing cost is comprised of machining and tooling costs (which are affected by machining cond...
Capacity allocation problem in flexible manufacturing systems: branch and bound based approaches
ÖZPEYNİRCİ, SELİN; Azizoğlu, Meral (Informa UK Limited, 2009-01-01)
This study considers an operation assignment and capacity allocation problem that arises in flexible manufacturing systems. The machines have limited time and tool magazine capacities and the available tools are limited. Our objective is to maximise total weight of assigned operations. We develop a branch and bound algorithm that finds the optimal solutions and a beam search algorithm that finds high quality solutions in polynomial time.
Bi criteria flexible assembly line design problem with equipment decisions
Pekin, N.; Azizoğlu, Meral (Informa UK Limited, 2008-01-01)
In this paper, we address the assembly line balancing and design problem of assigning tasks and equipment to work stations where there are several equipment alternatives for each task. We consider minimizing the total equipment cost and the number of work stations criteria. We aim to generate efficient solutions with respect to these criteria and propose a branch and bound algorithm whose efficiency is enhanced with powerful reduction and bounding mechanisms. We find that our algorithm is capable of solving...
Capturing knowledge in construction projects: Knowledge platform for contractors
Kivrak, Serkan; Arslan, Gokhan; Dikmen Toker, İrem; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2008-04-01)
Managing knowledge effectively is critical to the survival and advance of a company, especially in project-based industries such as construction. However, capturing knowledge in construction projects is a tedious task, as knowledge is usually experience based, tacit, and hard to pass on to others. In this study, a survey was carried out among eight leading Turkish construction contractors that are operating within the international construction market. The specific objectives of this survey are to find out ...
Collaboration environments for construction: Implementation case studies
Erdogan, Bilge; Anumba, Chimay J.; Bouchlaghem, Dino; Nielsen, Yasemin (American Society of Civil Engineers (ASCE), 2008-10-01)
Although emerging technologies offer the construction industry many opportunities for computer supported collaboration environments, the companies adopting these technologies usually fail in achieving the full benefits from their implementations. The reason for this is found to be focusing too much on the technical factors and ignoring or underestimating the factors related to change, implementation, human and organizational factors, and the roles of the management and end users. Each new information techno...
