Contract costing in outsourcing enterprises: Exploring the benefits of discrete-event simulation

Capacity flexibility allocation in an outsourced supply chain with reservation

“…Liston et al, 2007). The rise of contract manufacturers that often serve a number of competing outsourcers, results in new challenges and complexities.…”

Supply Chain Reactivity Assessment Regarding Two Negotiated Commitments: Frozen Horizon and Flexibility Rate

“…In literature, we distinguish for example [5], [6] where the authors aim through their research to get optimal purchasing policy. We notice that majority of works are optimization models under contractual context based on stochastic modelling [7] or continuous modelling [8]. Our research is quite different in term of problem modelling and objective, in one hand we propose a discrete planning model (like [9]) rather infrequently used in this field.…”

“…Flexibility rate concept has been studied in literature. These are some definitions founded: for [7], it is an upside and downside flexibility bounds of order quantity. Bassok & Anupindi in [8] considers a model in which the amount of increase or reduction in the order for a given period is limited to a percentage of the current order for the period.…”

Multidimensional evaluation of value added networks

“…The longer the forecast has to be the more a stochastic model is needed, due to inherent uncertainties. Analytical models are too rigid and lack the required flexibility to cope with the complexity of the systems to be modelled, while a simulation approach is able to model these complex stochastic real-world systems [6]. A simulation has three basic characteristics: It is a quantitative model, it is dynamic, and the model is not solved by mathematical analysis, what means, that it cannot solve problems; it can only provide information from which solutions can be inferred [7].…”
