Three simple, single pass multi‐stage lot‐sizing heuristics are examined using simulation. The heuristics are based on using different cost policies in single stage lot‐sizing procedures when applied to a multi‐stage setting. The focus is on the echelon holding cost policy and its...

This paper is concerned with the problem of maintaining open order due dates in job shops that plan and schedule their operations using Material Requirements Planning (MRP) methodology. Two different techniques for dealing with open order due date changes are analyzed using customer service...

In this paper, we develop a simple algorithm for obtaining the global solution to a small scale fixed-charge transportation problem (FCTP). The procedure itself is very quick. The proposed method solves FCTP by decomposing the problem into series of smaller sub-problems, which is novel and can...

In this paper we present a new approximation for computing lower bound for the fixed charge transportation problem (FCTP). The lower bounds thus generated delivered 87% optimal solutions for 56 randomly generated small, up to 6×10 in size, problems in an experimental design. For somewhat...
