Abstract:There is a growing trend of information sharing within modern supply chains. This trend is mainly stimulated by recent developments in information technology and the increasing awareness that accurate and timely information helps firms cope with volatile and uncertain business conditions. We model a periodic-review, single-item, capacitated stochastic inventory system, where a supply chain member has the ability to obtain advance capacity information (‘ACI’) about future supply capacity availability. ACI is used to reduce the uncertainty of future supply and thus enables the decision-maker to make better ordering decisions. We develop an easily applicable heuristic based on insights gained from an analysis of the optimal policy. In a numerical study we quantify the benefits of ACI and compare the performance of the proposed heuristic with the optimal performance. We illustrate the conditions in which the procedure is working well and comment on its practical applicability.

Title:Hevrističen pristop k uravnavanju zalog z informacijo o razpoložljivosti oskrbe
Abstract:V sodobnih oskrbnih verigah je v zadnjih dveh desetletjih močno prisoten trend izmenjave informacij, ki omogočajo izboljša­nje poslovanja posameznih podjetij, kot tudi celotne oskrbne verige. S pomočjo natančnih in pravočasnih informacij, katerih prenos je z nedavnim razvojem informacijskih tehnologij močno olajšan, se podjetja uspešno spopadajo s spremenljivimi in negotovimi pogoji poslovanja. V članku predstavimo model uravnavanja zalog s periodičnim spremljanjem zalog v pogojih nee­nakomernega stohastičnega povpraševanja z omejeno zmogljivostjo oskrbe, kjer ima člen oskrbne verige dostop do informa­cije o razpoložljivosti oskrbe. Informacija o razpoložljivosti oskrbe zmanjša negotovost prihodnje oskrbe in omogoči managerju učinkovitejše naročanje. Na podlagi glavnih vpogledov pridobljenih z analizo optimalne politike naročanja razvijemo praktično uporabno hevristično metodo. Z numerično analizo določimo vrednost informacije o razpoložljivosti oskrbe in prepoznamo scenarije, kjer je ta največja. Ob tem na podlagi primerjave med rezultati optimalne politike naročanja in predlagane hevristike izmerimo natančnost le-te in podamo pogoje, ki morajo biti izpolnjeni, da hevristika doseže želeno natančnost.
