    • Optimizing production capacity and safety stocks in general acyclic supply chains

      Ghadimi, Foad; Aouam, Tarik; Vanhoucke, Mario (Computers and Operations Research, 2020)
      This paper addresses the joint optimization of production capacity and safety stocks in supply chains under the guaranteed service approach (GSA). The integrated problem is formulated as a mixed integer nonlinear program (MINLP) and solution procedures are proposed in the cases of general acyclic and spanning tree networks. For general acyclic supply chains, the integrated problem is solved using a Lagrangian decomposition method which iteratively solves capacity planning and safety stock placement subproblems, and adds budget feasibility constraints to strengthen the Lagrangian decomposition lower bound. When the supply chain has a spanning tree structure, an efficient Lagrangian relaxation heuristic dualizes the budget constraint and solves the relaxed problem using a dynamic programming algorithm. Computational experiments on real-world instances show that the Lagrangian decomposition method is able to solve all instances within 0.1% optimality, while a state-of-the-art solver is unable to provide feasible solutions for large instances. In the case of spanning tree networks, the proposed Lagrangian relaxation heuristic finds optimal or near-optimal solutions and greatly improves running time in comparison to the Lagrangian decomposition method. In addition, numerical experiments show that savings can be achieved through joint optimization of capacity and safety stocks.

    • Or Noir Customised Chocolate at Barry Callebaut

      Vereecke, Ann; Parrez, Elke (2011)
      Barry Callebaut is a fully integrated chocolate company with worldwide presence in 26 countries. The company is world leader in producing chocolate and compound products with an estimated volume of 524.000 tons in 2006. In addition to its standard product range of high volume, made-to-order chocolate, Barry Callebaut has introduced a new service, targeted at its artisan customer. The new initiative, 'Or Noir', allows the artisan customer to create his/her own chocolate, in small volumes (500kg), based on a selection of a number of region-specific cocoa beans. The challenge has been to offer this customisation without incurring the high cost that would be associated with the production of small batches in a production process that had been designed for large volumes. The company manages to do so through a creative supply chain design, in combination with an advanced product development system that allows the customer to design the preferred chocolate.

    • Organisaties op scherp

      Van den Broeck, Herman; Mestdagh, Steven (2002)
      In tijden van verandering biedt dit boek een onmisbaar vangnet voor elke manager. Het schetst op speelse maar diepgaande wijze het strijdtoneel waarop organisaties zich momenteel bevinden. 'Organisaties op scherp' reikt onmisbare stutten aan: het geeft aan hoe men opbouwend tegen verandering kan aankijken en waar zich de mogelijkheden bevinden om verandering om te toveren tot een boeiend en uitdagend gebeuren.$ Door te veranderen zoeken organisaties een plaats tussen chaos en orde. De auteurs tonen aan hoe deze twee eeuwige vijanden met elkaar verzoend kunnen worden. Ze geven aan hoe organisaties zich overeind kunnen houden in een omgeving waarin verandering dagelijkse kost is. Daartoe reiken ze onmisbare ingrediënten aan voor een geslaagd veranderingsproces.

    • Organisation multimedial: Zum polyphonen Programm der nächsten Organisation

      2010
      Die Zeiten, in denen Computer nur eine Funktion hatten, sind vorbei: Heutige Computer sind Kommunikationsmittel, Zeitnehmer, Kalender, Musikinstrument und -abspielgerät, Notizblock, Ablagesystem, Spielzeug, Wettervorhersage und Visitenkarte in einem. Die Organisation der Computergesellschaft scheint diese Entwicklung bislang verschlafen zu haben, kultiviert sie doch unbeirrt das Selbstverständnis der monofunktionalen Expertenorganisation: Bank? Wirtschaft! Partei? Politik! Schule? Bildung! An der Schwelle zur nächsten Gesellschaft entlarvt sich dieses Denken endgültig als alltagstheoretischer Kurzschluss: Die Bank ist längst auch Kunstmäzen, die Kirche Machtfaktor, die politische Verwaltung muss sich wirtschaftlich rechnen, und die Universität bekommt in aller Öffentlichkeit ihre „third mission“ übertragen. So zeigen die Beiträge des vorliegenden Bandes: Auch die Organisation der nächsten Gesellschaft ist multimedial. Und sie fragen, was das für ihre Identität bedeutet.
