Sales and operations planning (S&OP) is a key business process to match customer demand with supply capabilities in the medium term. Coordination mechanisms play a pivotal role within S&OP to align business strategy and operational planning as well as the involved business functions and supply...

In this paper we extend and apply MRP theory towards reverse logistics including the considerations of transportation consequences. Our aim is to demonstrate the versatility obtained from using MRP theory when combining Input–Output Analysis and Laplace transforms. This enables an analysis of...

A challenge for car manufacturers is to adjust rapidly and efficiently the production capacities with a volatile market demand and despite distant suppliers. In this paper, we consider a sales and operations planning problem based on the actual situation of Renault, a French global automobile...

Asset utilization is a major mid-term lever to increase shareholder value creation. Since rough-cut planning of capacity (dis-)investments is performed at the long-term level, detailed timing of adjustments remains for the mid-term level. In combination with capacity control measures, capacity...

We develop a deterministic optimization model that incorporates carbon emissions in a multi-echelon production-inventory model with lead time constraints. We impose that each customer order must be delivered within the due date fixed by the customer. The quantity that cannot be delivered on time...

We consider a decentralized supply chain consisting of a supplier and a retailer facing price- and lead-time-sensitive demand. The decision process is modelled by a Stackelberg game where the supplier, as a leader, determines the capacity and the wholesale price, and the retailer, as a follower,...

This paper develops an optimal replacement strategy for capital intensive equipment with long delivery lead time. The strategy is based on an extended version of the real options approach to repeated replacement decisions, in which the goal is to determine the operating cost and delivery...

By relaxing the long-term assumption of the deterministic lead time, recently three coordinated vendor–buyer models with exponential distribution of lead time in a two-stage supply chain were presented. The vendor produces a product at a finite rate and delivers the lot to the buyer with a...

This paper refers to a hierarchical production planning system in a make-to-order environment. A challenging task in this context is to determine good production parameter settings in order to benefit from established planning methods. We present a framework for hierarchical production planning...

We consider the problem of planning future order releases in hierarchical production planning and control systems. An established research direction is the clearing function concept: The planned material flow through a production unit is modeled by inventory balance equations for WIP and final...
