We present a nonparametric 'revealed preference' methodology for empiri- cally analyzing collective consumption behavior. First, we introduce an integer programming (IP) methodology for testing data consistency with collective con- sumption models that account for publicly as well as privately...

The design of computer experiments is an important step in black box evaluation and optimization processes.When dealing with multiple black box functions the need often arises to construct designs for all black boxes jointly, instead of individually.These so-called nested designs are used to...

through the network. Afterwards, fleet scheduling creates a schedule for vehicles operated in the network. The strong relation … between flow routing and fleet scheduling makes it difficult to optimise the network cost. Due to this complexity, fleet … scheduling and network design are usually decoupled. We propose a new tactical network design model that is able to include fleet …

In this paper we discuss a solver that is developed to solve set partitioning problems.The methods used include problem reduction techniques, lagrangean relaxation and primal and dual heuristics.The optimal solution is found using a branch and bound approach.In this paper we discuss these...

This paper provides a survey of simulation in supply chain management.It reviews four types of simulation, namely spreadsheet simulation, system dynamics, discreteevent simulation, and business games.Which simulation type should be applied, depends on the type of managerial question to be...

In practice, many package transportation companies lower their costs by hiring outside carriers to serve orders that cannot be served efficiently by their own trucks. The problem which takes the order outsource option into account is the Vehicle Routing Problem with Private Fleet and Common...

A generalization of processing problems with restricted capacities is introduced.In a processing problem there is a finite set of jobs, each requiring a specific amount of effort to be completed, whose costs depend linearly on their completion times.The new aspect is that players have interest...
