The basic Vehicle Routing and Scheduling Problem (VRSP) is described followed by an outline of solution approaches. Different variations of the basic VRSP are examined that involve the consideration of additional constraints or other changes in the structure of the appropriate model. An...

Multi-echelon distribution systems are quite common in supply-chain and logistic systems. They are used by public administrations in their transportation and traffic planning strategies as well as by companies to model their distribution systems. Unfortunately, the literature on com- binatorial...

Let R be the set of nonnegative matrices whose row and column sums fall between specific limits and whose entries sum to some fixed h 0. Closely related axiomatic approaches have been developed to ascribe meanings to the statements: the real matrix fe R and the integer matrix a ~ R are...

replies to all probabilistic beliefs over the set. We present an algorithm that computes all minimal sCURB sets in any given … finite game. Runtime measurements on two-player games (where the concepts of CURB and sCURB coincide) show that the algorithm … is considerably faster than the earlier developed algorithm, that of Benisch et al. (2006). …
