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.

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.
