in this paper, the researchers have investigated a concatenated robot move (crm) sequence problem and minimal part set (mps) schedule problem with different setup times for two-machine robotic cell. they have focused on simultaneous solving of crm sequence and mps schedule problems with different loading and unloading times. they have applied a simulated annealing (sa) algorithm to provide a go...
In production planning, sequence dependent setup times and costs are often incurred for switchovers from one product to another. When setup times and costs do not respect the triangular inequality, a situation may occur where the optimal solution includes more than one batch of the same product in a single period — in other words, at least one sub tour exists in the production sequence of that ...
Supply chain management in second half recent century extended so much and in current century this extension is continued. One of the scopes that to be interested is extension and adaptation of production and inventory control policy, under just in time philosophy, for material and production control in supply chain. Hence in this paper we will adapt pull-push CONWIP (constant work in process)...
Disaster relief logistics is one of the major activities in disaster management. The significance of accounting for uncertainty in such context stimulates an interest to develop appropriate decision making tools to cope with uncertain and imprecise parameters in relief logistics system design problems. This paper proposes a multi-objective possibilistic non-linear programming model (MOPNLP) t...
