Dear All, next Monday, the 1st of June, from 11:00 onwards, in IDSIA’s meeting room: Rossella Pozzi TITLE: Introducing capacity constraint in multi-product manufacturing environments ABSTRACT: The work proposes two models to incorporate the capacity constraint in multi-product manufacturing environments. In the first manufacturing environment, production is managed according to a pull policy, in which production is regulated by minimum and maximum inventory levels on each item (i.e., a min-max inventory policy). In particular, the work aims at developing a capacity-constrained version of the classical Economic Order Quantity (EOQ) model (Harris, 1913) exploiting the analogy between a multi-product production system with finite capacity and a hybrid system. The specific hybrid system considered as a reference is the “switched arrival system” proposed by Chase et al. (1993). In this framework, the pull policy of the production system is the equivalent to the control of the hybrid system. A linear programming model is developed to identify the minimum and maximum inventory thresholds on each product that minimize the distance between the average order quantity of each item and the corresponding classical EOQ (Harris, 1913). In the second manufacturing environment, production is managed according to a capacity-constrained push policy releasing the constraint related to lead times pre deterined (a priori). In particular, the work aims at developing a capacity-constrained version of the classical Material Requirements Planning (Orlicky, 1976) by means of linear programming. Fernanda Strozzi TITLE: Bibliometrics and Citation Network Analysis of Selected Topics in the Field of Wireless Sensor Networks. ABSTRACT: A fast-developing topic in field of ad-hoc sensor networks concerns the development of low energy-consumption wireless sensor systems to detect the emergence of coherent signals indicative of certain phenomena such as, for example, security threats or structural performance criteria in widely distributed structural elements. The range of technical fields related to the development of such systems is very broad, encompassing power electronics, network protocols and connectivity, and mathematical methods for data analysis. Given the ever-increasing literature output, it is sometimes difficult to garner an overview of the main research areas, who conducts it, and how they are connected. In this presentation an overview of selected topics retrieved from the Web of Science Core collection will be presented and post-processed using graph analysis methods to detect connectivity and salient features between authors, funding agencies and research fields.
