Local Container Drayage Problem (LCDP) refers to the optimization of process planning and scheduling container trucks between a terminal customers offer door-to-door service in local area. The time required for (un)packing containers at customers’ sites are often relatively long uncertain due current work level unexpected deviations operational situations, which has significant influence on tra...

  Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problems are co...

In this work we study a routing and scheduling problem for home care business. The is composed of two conflicting objectives, therefore it as bi-objective one. We obtain the Pareto frontier small size instances using AUGMECON2 method and, bigger cases, developed an heuristic algorithm. also obtained some preliminary results that show algorithm has good behaviour.

in this paper the real-world occurrence of the multiple-product multiple-constraint single period newsboy problem with two objectives, in which there is incremental discounts on the purchasing prices, is investigated. the constraints are the warehouse capacity and the batch forms of the order placements. the first objective of this problem is to find the order quantities such that the expected ...

We present an algorithm to solve a bi-level multi-objective fractional integer programming problem involving fuzzy numbers in the right-hand side of the constraints. The suggested algorithm combine the method of Taylor series together with the Kuhn Tucker conditions to solve fuzzy bi-level multi-objective fractional integer programming problem (FBLMOFIPP) then Gomory cuts are added till the int...
