Thesis
Full-text available
By balancing medium-term demand and supply, tactical planning enables manufacturing firms to realize strategic, long-term business objectives. However, such balancing in engineer-to-order (ETO) and configured-to-order (CTO) operations, due to the constant pressure of substantial complexity (e.g., volatility, uncertainty, and ambiguity), induces fre...
Article
Full-text available
The challenging demand-supply balancing in engineer-to-order (ETO) environments is often attributed to complexity. This study expands the understanding of managing complexity to obtain demand-supply balancing, focussing on the tactical planning logic of the order fulfilment process. An in-depth single case study was conducted and data describing th...
Article
Full-text available
Fulfilling customer orders in engineer-to-order (ETO) settings entails customization and, thus, greater complexity: detail and uncertainty. Tactical planning aims at demand-supply (DS) balancing by ensuring cross-functional integration (CFI), which incorporates coordination as one dimension. This study uses a case study approach to identify the key...

In engineer-to-order (ETO) supply chains (SCs), the importance of information flows is high compared to make-to-stock (MTS) SCs due to the demand intake being dependent on engineering activities like bid preparation and product customization. Demand-driven material requirement planning (DDMRP) holds promising benefits for material flows on the top...

This paper explores the uncertainty related to medium-term engineering needs considering sales and operations planning (S&OP). The areas of uncertainty and how they are addressed by S&OP are investigated in an engineer-to-order setting. Uncertainties stem from customer orders and critical competences and are minimized through integrating engineerin...
Conference Paper
Purpose Sales and operations planning have a long history in practice and has been researched extensively. It has been proposed that this tactical concept needs to be aligned with a more operational, short-term concept, hence the purpose of this paper is to investigate how sales and operations execution (S&OE) can enhance the performance of a suppl...

Purpose The purpose is to explore how OEMs generate instabilities in material delivery schedules ‎within automotive supply chains. ‎ Design A multiple case study of three automotive OEMs were conducted to collect qualitative and ‎quantitative data as to explore factors causing and amplifying schedule instability measured ‎by inaccuracy and nervousn...
Thesis
Full-text available
Tactical planning is implemented to balance customer demand and supply capacity within a medium-term and to avoid under- and overcapacity. In engineer-to-order (ETO) environments, under- and overcapacity lead firms to incur substantial costs that can easily wipe out profit margins. ETO-oriented markets like the construction and capital goods sector...
Conference Paper
Purpose: To understand how cross-functional integration (CFI) increases input data quality and enhances information processing efficiency in Engineer-to-Order (ETO) environments. Methodology: The empirical study focuses on the order acceptance phase of the order fulfilment process in two ETO-oriented companies. A literature review and a multi-case...
Conference Paper
The purpose is to explore what context dependencies within the planning environment of the construction industry that need to be considered designing tactical planning processes. The preliminary result using a Delphi study including architects, clients, contractors, researchers, and suppliers indicates that the top five most important context depen...

The study explores the role of the bid preparation process (BPP) in the Engineer-to-Order sector for achieving supply-demand balance and business alignment. Based on literature and a case study from the construction industry, three main decisions within the bid preparation process are found to have mid-term impacts on supply-demand balancing and bu...

At the commencement of any new concept introduction pertaining to a product or a service, a lot of ambiguity accompanies the paths of development. Consequently, companies allocate uncertain figures in their budgets during the concept phases of new product development (NPD) projects, which could require delays for years before taking the shape of a...

Automotive industry is currently characterized by very fierce competition in which an automaker has no choice but to run at the highest speed to survive. Challenges are too many, but design as a function is in the center due to its tight connection to time to market and competitive advantage capabilities such as production flexibility, speed, cost...

One important lesson out of many from practice-based design of Information Systems (ISs) is that technologies designed at distance are incapable of efficiently and effectively matching the distant needs, and there will be – as usual – substantial reworking to transform these technologies into the desired state. Further, he follow this lesson by the...

Open innovation (OI) concept emerged at the beginning of 2000. It was first coined by Henry Chesbrough after he observed the competitive advantages collaborative innovation could gain. Even though the term of OI became widespread, many large enterprises continue ignoring using it due to the organizational and corporate culture that tend to preserve...

Question
I have a well-described planning problem at a conceptual level, and I know how to model it on software. However, I do not precisely know how to sufficiently document the discrete-event simulation model, which is the result in this case. For instance, do I need to describe the underlying deterministic model mathematically first? I appreciate any suggestion for a guide in regards to this issue. Leaving a comment with a reference for a good paper that does the same helps handsomely. Ideally, your example addresses a capacity planning problem.
Question
Are there theoretical lenses to analyze variability (identifying causes of variations) qualitatively? Not sure if e.g. complexity theory, organization theory, contingency theory may be helpful.
Question

2- Demand planning
3- Pre-S&OP: reconciliation of all plans
4- S&OP Implementation

Project
The project’s point of departure is generally low forecast/delivery schedule accuracies, with negative impact on tied-up capital, transport costs, volume flexibility and environment in automotive industry supply chains. The aim is to generate a best practice description of how planning information is shared and used in the supply chains, and develop and field test new methods and models for measuring, visualizing and predicting delivery schedule variations in supply chains.
