Part-mix allocation between automated and conventional manufacturing

The overall part-mix of a production system is allocated optimally between the existing conventional facilities and planned automated system to be acquired. Approximate mean value analysis (MVA) is utilized to evaluate performance of the automated system under trial part-mix allocations. Cost of processing and WIPs are taken as the sources of operational costs. Cost minimizing route allocations when alternatives exist are handled by a search procedure.

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.
Flexibility analysis: a methodology and a case study
Kahyaoglu, Y; Kayaligil, S; Buzacott, JA (Informa UK Limited, 2002-11-10)
A methodology for analysing manufacturing flexibility is proposed. A real-life case is discussed to demonstrate the proposed methodology. The case involves the grinding operations of an engine manufacturer. As an integral part of the methodology, statistical analyses using response surface methodology are carried out. Potential applications of the proposed methodology are discussed. Planning models and flexibility measure used are outlined in the appendices.
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...
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...
Rebalancing the assembly lines with total squared workload and total replacement distance objectives
Girit, Utku; Azizoğlu, Meral (Informa UK Limited, 2020-01-01)
Assembly line balancing is an important and well recognised operations research problem. The current line balance may not stay optimal, even feasible, due to the disruptions in one or more workstations. In this study, after the disruption, we aim to rebalance the assembly line by considering the trade-off between workload balancing (fairness measure) and total replacement distance for the tasks assigned to the different workstations (stability measure). We try to generate all non-dominated objective functio...
