“…As an alternative, the consumption-oriented demand planning can be used by applying stochastic methods using the known historic consumption [43]. Stochastic methods determine the expected demand with the support of statistical forecast processes, while heuristic methods define the demand forecast based on subjective estimations of the planner [44].…”

The current global market situation pursues high adaptability, but why? Complexity due to mass customization is greater than ever. Globalization is no longer a theory but a fact that makes disruptions in the globalized supply chain a major risk for operations. In this context, customers demand novelty and unique experiences. These are the main drivers for market success. Therefore, existing products are now in continuous states of change with shortened product lifecycles. The purpose of this article is to analyze the impact of new market entries and product changes along the lifecycle as well as supply chain disruptions in supplier inventory levels. The goal is to minimize costs by achieving a given service level with a market-oriented procurement planning model. The model pursues minimizing the time needed to align the system with the market and, therefore, the adaptability of the system. The research compares classical inventory management models with the new proposed approach by means of simulation with the system dynamics methodology. The results show how the proposed model increased the delivery service level, reduced inventory costs, and increased the utilization of resources due to lower demand uncertainty. Therefore, the developed model is able to plan the inventory supply with a low risk of stock outages. The conclusion proposes a differentiated forecasting and inventory strategy depending on the product lifecycle stage. The developed market-oriented procurement planning model provides guidance for inventory managers regarding how to optimize their operations as an opportunity within the fourth industrial revolution to develop information technology (IT) systems to gather and utilize demand and inventory data with real-time efficiency.

“…This completes the proposal for submission to the customer. [3,14] In this paper, the focus is mainly on the cost estimation of customized product variants in the offer phase. Furthermore, the cost estimation of changes that arise due to internal or external causes during the order processing, is explained in more detail.…”

Abstract:In Engineer-to-Order (ETO) manufacturing the price of products must be defined during early stages of product design and during the bidding process, thus an overestimation of product development (PD) costs may lead to the loss of orders and an underestimation causes a profit loss. What many ETO systems have in common is that the products have to be developed based on different customer requirements so that each order usually results in a new variant. Furthermore, many customer requirement change-requests may arise in different phases of the PD, which is to be considered properly. Thus it is utmost important for ETO systems to have an accurate cost estimation in first stages of the product design and to be able to determine the cost of customer requirement changes in different phases of PD. This paper aims to present a cost estimation methodology as well as a cost estimation model, which estimate the cost of products by relative comparison of the attributes of new product variants with the attributes of standard product variants. In addition, as a necessity in ETO manufacturing, the cost calculation of customer requirement changes in different phases of PD is integrated in the presented method.
