In order to resolve disturbances, which can affect a network transport, a regulation process has to be performed by a real-time regulator who has a complex decision-making role including disturbance detection, practicable decisions elaboration and evaluation; and choice decision to adopt.

A few research works have proposed a BPMN metamodel fully compliant to the BPMN specification. In a recent project called PERCOMOM and based on MDA approach, we have noticed the need to a BPMN metamodel and a transformation tool to handle automatically transformations from a BPMN model to an XML model. In this paper, we have proposed a BPMN metamodel and a set of transformation rules based on ATL to automatically handle those transformations. We have also applied and validate our approach on some samples of BPMN models.

The performance evaluation of the Vehicle to Vehicle and Vehicle to Infrastructure V2X communication system is an important step before its integration into vehicles and its probable real deployment. In this paper, the physical layer PHY of the upcoming vehicular communication standard IEEE 802.11p is an issue of our study. A near realistic IEEE.802.11p PHY model, with all the associated phenomena, is implemented in V2X situation through different scenarios. The series of simulation results carried out perform data exchange between high-speed vehicles as well as the vehicles and the roadside infrastructure over Rician channel model. We underlined several and important propagation channel parameters which affect both the physical layer network performance and the quality of transmission. The Bit Error Rate BER versus Signal to Noise Ratio (SNR) of all coding rates is used to evaluate the performance of the communication systems.

Traceability is a needed strategic service in any production context. It can be used to improve security, control quality, manage complex chains, minimize recalls, limit incurred risk and reassure consumers. In this paper the problem of minimizing the quantity of recall and the number of batches constituting a given finished product is treated, when products are characterized by a 4-level “disassembling and assembling” bill of material. A mathematical Mixed Integer Linear Programming model (MILP) is proposed and the results of experiments obtained with CPLEX software are presented.

Outsourcing has become an increasingly popular option for many organisations. In order to clarify the motivation for logistics outsourcing, this paper analyses the perceived advantages and limitations. This article presents an empirical research on thirty Textile-Clothing companies operating in Tunisia. It was carried out to compare between the enterprises which outsource production and distribution functions in terms of benefits and decision-making for choosing third-party logistics. We develop and validate a survey instrument used to collect data for this study. Results based on the analysis of data indicate that most of these users are satisfied with the services providers.

Over the last years various extensions of the Vehicle Routing Problem (VRP), considering complicated constraints encountered in the real-life, has been studied. These extensions are often coined as rich VRP. In this work, we tackle a rich VRP namely the Multi Compartment Multi Commodity Heterogeneous Fixed Fleet Vehicle Routing Problem with hard Time Windows (MCMCHFFVRPTW). The objective of the problem is to determine an assignment of the non-intermixable products into vehicle compartments of different sizes and a set of vehicle routes of total minimum distance and minimum waiting time while satisfying the customer demands. The main contribution of this paper is to identify the most relevant instance factor for this problem. Thus, we develop a generic parameterized mathematical model and a data set generator able to produce a great variety of instances based on various service policies and fleet characteristics. New sets of instances were generated by systematically varying design parameters. First, an exact resolution for four models using CPLEX 10.0 is provided. Second, we resorted to the desirability method using the Design Expert 7.0 software to find a good set of conditions. This study allows the companies identifying the best policies to follow and the essential components to reduce costs.

The delivery of goods from a warehouse to local customers is important and practical problem of supply chain management. Current customer demand changes from day to day. If the total demand is greater than the whole capacity of the internal fleet, the use of the external carrier becomes necessary. Thus; it may be more economical to use an external carrier instead of an internal vehicle to serve one or very few customers. In this work we attempt to model the company problem. We first try to assign vehicles to warehouse and determine the private fleet size needed at each one by taking into account the interventions of preventive maintenance. Then we develop a second model that routes this limited truck from two central warehouses to customers' with the option of using an external carrier.
