Decisions regarding the allocation of demand centres to distribution facilities over a multiperiod planning horizon have disjointed single-period implications. However, interperiod effects of assignment decisions are potentially as significant. Often these dynamic forces are neglected in distribution system planning. This paper focuses on approaches for analyzing the consequences of interperiod allocation relationships.
A mathematical program is developed to provide a comprehensive treatment of dynamic implications and their interactions with single-period effects. Then, special cases of the model are examined. The paper shows that these specific approaches contain dynamic counterparts of treatments which are used in static (single-period) formulations. The general model and its special cases are the basis of a conceptual structure that is presented as a frame of reference for multiperiod allocation analysis.
