We consider the optimal pricing problem in a service facility in order to maximize its long-run average profit per unit time. We model the facility as a queueing process that may havefinite or infinite capacity. Customers are admitted into the system if it is not full and if they are willing to...

In this thesis, we study the repair shop scheduling problem(repair-to-stock) and the production/inventory system pricing and production scheduling problem(make-to-stock). For both types of problems, we compare the performance of different scheduling policies. For the make-to-stock type problem,...

Primäres Ziel dieser Arbeit war die Entwicklung neuer heuristischer Lösungsverfahren für die logistische Tourenplanung bei restringierendem Anhängereinsatz (engl. Truck and Trailer Routing Problem). Kennzeichnend für dieses kombinatorische Optimierungsproblem ist, dass Fahrzeuge einen...

Die Arbeit präsentiert ein lineares Optimierungsverfahren, das Teilnehmern einer Workshopveranstaltung Plätze in Workshops zuteilt, basierend auf persönlichen Präferenzen.Diverse Nebenbedingungen werden dabei beachtet. In einer zweiten Stufe wird das Ergebnis weiter verbessert, indem private...

For the past several years, competing resource demands within BPA have forced the Agency to stretch Operations, Maintenance and Replacement (OM R) resources. There is a large accumulation of tasks that were not accomplished when scheduled. Maintenance and replacements and outages, due to...

Search and optimization in the context of blackbox objective function evaluation subject to blackbox constraints satisfaction is the thesis of this work. The SEARCH (Search Envisioned As Relation and Class Hierarchizing) framework introduced by Kargupta (1995) offered an alternate perspective of...

The SEARCH (Search Envisioned As Relation and Class Hierarchizing) framework developed elsewhere (Kargupta, 1995; Kargupta and Goldberg, 1995) offered an alternate perspective toward blackbox optimization -- optimization in presence of little domain knowledge. The SEARCH framework investigates the...

The development of an expert system for instrumentation and control operations is sometimes particularly difficult because (a) the expert system must implement the consensus opinion of a group of several human experts in all circumstances, (b) there may be 20 or more complex, dynamic,...

In this paper we consider the problem of grouping machine and human resources in mixed model assembly process so that sequencing and scheduling decisions may be performed more efficiently. Resource aggregation can potentially and significantly improve production efficiency and throughput by...

In this paper, Statistical Activity Cost Analysis (SACA) is used to identify the interaction of mutually dependent physical and financial aspects of a fixed asset-like system configuration. The novelty of the approach is, having established a rational description of the uncertainty inherent in...
