This paper addresses the problem of transportation procurement process in a stochastic context and proposes a resolution approach aiming to obtain an optimal policy over a finite planning horizon. Based on a conceptual framework which integrates both strategic and operational decision making levels, this paper addresses the problem from an operational point of view while integrating the transportation decisions already taken at the strategic level. Strategic decisions provide a set of core carriers selected using a combinatorial auction mechanism in which carriers compete by submitting package bids on shipper s' requests. Operational decisions involve a set of core and spot carriers competing to procure transportation services and ship loads from a set of warehouses to a set of distribution centres over a finite planning horizon. The problem is modelled as a Stochastic Linear Multistage Program and the Stochastic Dual Dynamic Programming SDDP is adapted to solve it. To illustrate the practical usefulness and the behaviour of the obtained results, experimentations and sensitivity analyses are carried out.

Shiphandling is deemed as a factor of safety operation of ferry which consists of several variables such as ship condition, shiphandling facility condition, navigation condition and weather condition. The presence of expert knowledge on the complexity of shiphandling difficulty could be utilised through fuzzy rule base and further it could be treated by fuzzy logic system. As the result, the shiphandling difficulty level in linguistic form could be determined and it could be used to form safety criteria of ferry operation in certain area, in this case through development of shiphandling difficulty model for ferry (SMDF). The improvement of SMDF as well as the simulation of model is conducted. As the result, SMDF could be used for assessing safety level of ferry operation through shiphandling aspect and further it could be used to develop standard criteria for ferry operation by regulator.

Wireless Sensor Networks (WSN) are employed in several applications, including military, medical, environmental and household applications. Among the most important problems in WSN are their vulnerability to faults and high energy consumption. Both of these problems require the implementation of fault distributed detection methods, capable of distinguishing faulty nodes from normal nodes while taking into account energy problems. Several approaches of distributed fault detection are proposed; for example, we include the Bayesian approach, which ensures a study oscillating between Theory of Signal Detection (TSD), fault tolerance and energy optimization by determining optimal parameters of the detection. It is in this context that our paper is inscribed, where we try to apply this approach in the industrial security's field. The Bayesian approach ensures a pre study of WSN's deployment in the dangerous chemical products stores and guarantees a best performing fault detection. The experimental simulations will testify that the proposed algorithm is able to provide a good detection performance while optimizing energy in WSN.

Information and logistics are two main problems in Tourism Supply Chain. Tourism Supply chain cooperation has become a critical success factor. Cooperation refers to the integration of different parts of an organization or different organizations in supply chain to accomplish a collective set of tasks and to achieve mutual benefits. Several researches focus on applying artificial intelligence to solving the problem. Semantic web services and Multi- Agent are two technologies with great potential. However, semantic web services need for an upper software entity able to deal with them and, on the other hand agent technology has historically suffered from a number of drawbacks that must be addressed. Integrating these two technologies in a joint environment can overcome their problems while strengthening their advantages. In this paper, the necessity for integrating these technologies and the potential benefits of their combination are analyzed. Based in this study we present our intelligent framework, provided a support of collaborative decision making in the context of Tourism Supply Chain.

The paper describes a multi-objective mathematical model for the Dial a Ride Problem (DRP) and an application of Multi-Objective Simulated Annealing (MOSA) to solve it. DRP is to take over the passenger from a place of departure to a place of arrival. In the DRP, passengers send transportation requests to an operator. The ultimate aim is to offer an alternative to displacement optimized individually and collectively. The DRP is classified as NP-hard problem that's why most research has been concentrated on the use of approximate methods to solve it. Indeed the DRP is a multi-criteria problem, the proposed solution which aims to reduce both route duration in response to a certain quality of service provided. Actually, during the system of transport on demand (TOD) there are many problems can inhibit the proper functioning of the system, such as failure of the car and bottling etc. We propose a resolution of the dynamic DRP using a service of TOD called TOD with Simulated Annealing (TOD-SA). The solution proposed in this paper enables both a reduction of travel time also the distance traveled.

This paper addresses a vehicle sequencing problem at multiple intersections under the framework of Autonomous Intersection Management (AIM). In the context of AIM, there is no more traffic signals. Autonomous vehicles are considered as independent individuals and the traffic control aims at deciding an efficient vehicle passing sequence. Since there are considerable vehicle passing combinations, how to find an efficient vehicle passing sequence in a short time becomes a big challenge. In this paper, we present a genetic algorithm based on these basic groups is designed to find an optimal or near-optimal vehicle passing sequence. Computational experiments and simulation results show that the traffic condition can be dramatically improved by applying our algorithm.

Intelligent Public Transportation Systems (IPTS) are a subsystem of Intelligent Transportation Systems (ITS), which aim to control public transportation networks, to maintain their performance, and to provide users (passengers and decision makers) with up-to-date information about trips and network operating conditions. To reach these aims, IPTS rely on several technologies that can be embedded within different control architectures. This paper introduces IPTS components and technologies, identifies the different types of data captured from the transportation network and exchanged between IPTS components, and shows ways to integrate technological components and data within IPTS architectures. A section is dedicated to review architectural design of some developed IPTS to control public transportation networks. Finally, some challenges are discussed and further research directions are highlighted.

Modern supply chains are very complex and suffer always from various risks. An effective supply chain management requires suitable strategies to mitigate them. In literature, there has been a range of research into risk in purchasing and supply, but little in global and integrated supply networks. This can be explained due to the huge number of risk variables and their direct and indirect interrelations that may suffer all supply chain partners. Therefore, for better risk management process, the risk prioritization step is vital. The purpose of this paper is to apply a structural modeling technique for risk analysis and prioritization through a real case study of Masmoudi pastry supply network. Firstly, thirty risk variables have been identified through literature survey, interaction with industry experts, and various interviews with the supply key managers. Secondly, MICMAC method is applied to recognize both direct and indirect relationships between these thirty risk variables, and to ascertain the most prioritized risk variables. This prioritization provides a useful tool to Masmoudi pastry managers to differentiate between independent and dependent risk variables and their mutual relationships which would help them to focus on those key variables that are most important for an effective risk mitigation management.
