Accurate response and postponement are two strategies for a firm to deal with demand uncertainty and better match supply with demand. Under accurate response, reactive capacity could be used for customized make-to-order (MTO) production according to customer demands. On the other hand, using...

In this paper the optimal sourcing decisions of a multi-product newsvendor prior to the selling season of the products are studied. To satisfy the uncertain demands, the newsvendor can either utilize speculative production, or anticipatively reserve capacity. During the selling season when...

In real life distribution of goods, relatively long service times may make it difficult to serve all requests during regular working hours. These difficulties are even greater if the beginning of the service in each demand site must occur within a time window and violations of routing time...

A simple augmented ∊-constraint (SAUGMECON) method is put forward to generate all non-dominated solutions of multi-objective integer programming (MOIP) problems. The SAUGMECON method is a variant of the augmented ∊-constraint (AUGMECON) method proposed in 2009 and improved in 2013 by...

In this paper, the value of correctly addressing uncertainty and risk in operational planning is studied in the context of the Vehicle Routing Problem with Stochastic Demands (VRPSD). The main issues analysed in this paper concern (1) the evaluation of different risk attitudes in planning...
