- We deal with a multi-echelon inventory system in which one warehouse supplies an item to multiple retailers. Customer demand arrives at each retailer at a constant rate. The retailers replenish their inventories from the warehouse that in turn orders from an outside supplier. It is assumed that shortages are not allowed and lead times are negligible. The goal is to determine replenishment policies that minimize the overall cost in the system. We develop a heuristic to compute efficient policies, which also can easily be used in a spreadsheet application. The main idea consists of finding a balance between the replenishment and the inventory holding costs at each installation. This new heuristic we compare with two other approaches proposed in the literature; the computational studies show that in most of the instances generated the new method provides lower costs.

Product costing in ten Swedish manufacturing companies

Journal article (peer-reviewed)abstract
- This paper presents the main results from case studies in 10 Swedish manufacturing companies concerning their product costing. The main purpose of the study is to find out what models of product costing the companies use, what allocation bases are applied. Several questions have been asked to the companies: What is the purpose of the product costing? Is a special product costing used for inventory valuation? Is full costing or variable costing used? How are depreciation costs and cost of capital treated? Is some sort of activity-based costing used? If so, which arethe cost drivers? The study is a case analysis, no questionnaires are used. The study presents arguments that a separation of product costing in “Activity-Based Costing” or “traditional costing” is not possible, but also that more “ABC-thinking” is necessary.

Economic lot scheduling problems incorporating a cost of using the production facility
- 2009
-
In: International Journal of Production Research. - : Informa UK Limited. - 0020-7543 .- 1366-588X. ; 47:13, s. 3611-3624

Journal article (peer-reviewed)abstract
- This paper considers scheduling the production of several different items on a single machine with constrained capacity, commonly known as the Economic Lot Scheduling Problem (ELSP). Most traditional approaches for the ELSP consider the sum of the setup cost and inventory holding cost and provide cyclic schedules that minimize this sum. In practice, there are not only costs for setups and inventory holding, but also costs for operating the production facility due to e.g. electricity, service, maintenance, tools, operators etc, which depend on the number of hours the facility is operating per working day. In this paper, we modify the traditional cost function to include not only setup and inventory holding cost but also a time variable cost for operating the production facility. The paper shows it is possible to adapt a previous heuristic procedure to this complemented cost. The model can help to determine cyclic schedules and the number of production hours per working day.
