TL;DR: The purpose of this paper is to identify to define and classify customization requirements and evaluate how generic modeling and configuration assistance within the CSP framework can fulfil the requirements.
Abstract: The purpose of this paper is, on the one hand, to identify to define and classify customization requirements and, on the other hand, to evaluate how generic modeling and configuration assistance within the Constraint Satisfaction Problem (CSP) framework can fulfil the requirements. The aim is to provide commercial configurator knowledge base designers with constraint based generic modeling elements for customizable industrial product. A first part recalls the main trends of the configuration problem. In a second part divided in four sections corresponding with different requirement set; each section proposes a definition of the requirement set, some CSP based modeling elements and a discussion about adequacy of relevant configuration assistance techniques.

TL;DR: A systematic review of the current state of research in travel time reliability, and more explicitly in the value oftravel time reliability is presented.
Abstract: Travel time reliability is a fundamental factor in travel behavior. It represents the temporal uncertainty experienced by users in their movement between any two nodes in a network. The importance of the time reliability depends on the penalties incurred by the users. In road networks, travelers consider the existence of a trip travel time uncertainty in different choice situations (departure time, route, mode, and others). In this paper, a systematic review of the current state of research in travel time reliability, and more explicitly in the value of travel time reliability is presented. Moreover, a meta-analysis is performed in order to determine the reasons behind the discrepancy among the reliability estimates.

TL;DR: A literature review of the platform concept with a special interest on the efficient product family development.
Abstract: After the industrial revolution, the literature has mentioned different “principles” to allow a better management of the production and product life cycle activities. For example the principle of standardization was first mentioned in the literature by an automobile engineer and placed in a real context by Henry Ford. Standardization has made possible the configuration of different products using a large set of common components. Another strategy called “modularization” was first mentioned in the literature in the 60s. The modularity proposed to group components of products in a module for practical production objectives. Today, modularity and standardization are promising tools in product family development because they allow to design a variety of products using the same modules of components called “platforms”. Using platforms allows important family design savings and easy manufacturing. In this paper we give a literature review of the platform concept with a special interest on the efficient product family development. This paper is organized as follows. Section 1 mentions the general context of modularity to develop product variety. Section 2 details the importance of product architectures in the literature for a modular design. Section 3 points on some important works that apply some modular and platform methodologies.

TL;DR: It was verified that sustainability has been mainly tackled by assessing economic and environmental aspects, leaving behind the social aspects, and it was found that optimization models applied to strategic level decisions are the most preponderant studies.
