“…This suggests room for improvements in both the managerial principles and procedures, and in the software support of these processes. Indeed, they may be considered the core of project-based enterprises, since the high customisation results in frequent changes of product design, process planning and production routines (Tu and Dean 2011), and resource usage has to be carefully handled and monitored.…”

This paper illustrates the results of an empirical study involving 21 engineer-to-order (ETO) companies, operating in the machinery-building industry. The study investigates the needs and requirements of such companies in terms of software support for governing the businesses, with particular emphasis on production planning and control (PPC) processes. An empirical analysis investigated two main aspects: (i) the set of business activities performed by the companies in the analysed industry and (ii) the relevant, high-level software functionalities required for the execution of such activities. As an answer to the observed compelling need for reviewing the general approaches to PPC in machinery-building companies, we develop an empirical, high-level production planning and scheduling reference framework, encompassing all the activities involved in the order fulfilment process.

“…On the contrary, the results highlight that three fundamental supporting processes ("project management", "planning" and "cost control") are not well formalized. This suggests room for improvements because these processes may be considered the core of project-based enterprises, since the high customization results in frequent changes of product design, process planning and production routines [8] and resource usage has to be carefully handled and monitored.…”

Abstract. In this paper, we focus on the One-of-a-Kind Production (OKP) industry, where each product is designed and manufactured based on specific customer requirements to a large extent, according to an Engineer To Order (ETO) approach. The paper illustrates an empirical study on the state-of-the-art of information systems supporting the leading processes in OKP companies. Through a set of 21 case studies in Italian companies producing special machines, we aim to: identify and investigate strengths and weaknesses of the main OKP business processes; analyze the ICT support and its level of integration among the different ICT solutions; identify levers for improvement, concerning organizational, methodological and informatics aspects; build a practical framework that could define and link the main processes in order to obtain a sort of guideline useful for re-engineering the processes, and laying the foundation for a new integrated ICT business template for OKP companies.

“…In practice, "manufactured-to-order" projects are generally named a one-of-a-kind project (OKP), which aims at producing highly customized projects at nearly mass production efficiency (Tu & Dean 2011). The project manager in OKP needs to deal with project activities classified under A, B, and D activity assumptions simultaneously.…”

The resource-constrained project scheduling problem (RCPSP) is a well-known and widely studied topic. The underlying problem assumes that non-preemptions and that constant resources are restrictions imposed on project activities, which are to be scheduled, subject to precedence relation and limited resource constraints. Project activities, in RCPSP, are classified under category A. The problem is expanded to include various other activity assumptions categories, such as B and C. In the Preemptive-RCPSP, project activities are classified under category B, which refers to the activity that can be implemented using constant resources and constant durations. In the Flexible-RCPSP, project activities are classified under category C, which refers to the activities that can be executed using flexible resources over flexible durations, and preemptions are not allowed. However, in One-of-a-Kind Production companies (OKP), such as the housing industry, plastic injection moldings, and RV manufacturing, all known as "manufactured-to-order" operations, the activities are classified under category D in addition to A, B, and C, simultaneously. Category D refers to the activities that can be executed using flexible durations and flexible resources, and preemptions are allowed. In this paper, therefore, we present a new effective model in order to deal with the projects that consist of all the previous activity assumptions simultaneously to generate feasible project schedules. Case studies are included, and the results show that the resources usage is increased and the project makespan is reduced.
