We address a data-based identification method of machine scheduling problems using timed Petri nets. A general machine scheduling model is represented by timed Petri nets with resource places. Given a set of machines and jobs, and their starting times and completion times of several machines, the objective is to find resource constraints of a given machine scheduling problem from input and output data. The problem is to find the connectivity of each resource place in the operational places. A mixed integer linear programming model is formulated to find an optimal connectivity of resource places to minimize the mean square error of the input and output data. An approximation algorithm is developed to apply larger instances. Numerical examples are provided to show the effectiveness of the proposed approximation algorithm.

We show how the concept of demurrage - a core principle of commercial shipping contracts - is at odds with efficient and environmentally friendly vessel operation and represents barriers to improving energy efficiency in maritime transportation. Because demurrage rates are higher than freight earnings in poor markets, shipowners order their ships to “rush-to-wait”, resulting in higher fuel consumption and ship-to-air emissions. We propose a new speed optimization model where demurrage is properly accounted for and show that the observed behaviour is rational for a profit-maximizing shipowner. Using a numerical example for Aframax crude oil tankers, we illustrate the economic effects of demurrage on vessel earnings and optimal speed.

Construction is one of the most hazardous industries compared to others. Although, system safety has been adopted, accidents continually occur with Thai and foreign workers. Particularly, the number accidents of foreign workers that trend increased due to language differences. The purpose of this research is to assess risks among Thai and foreign workers in construction companies using the Risk Assessment Model (RAM) to assess risk levels of each careers and accident types that happen to Thai and Foreign workers. The results from this study showed a different risk level between Thai and foreign workers of each careers, including types of construction accidents. In conclusion, this was found to be beneficial for predicting high-risk construction activities and preventing accidents that further happen.

In city logistics, some group of vehicles are usually assigned a certain fixed areas so that drivers get used to the route or the customer sites. Vehicles deliver materials regularly every time period at the same area. In other words, the customer demand can be placed in the similar area each time period. Thus, we may find the optimal route for the demand of two time periods instead of finding the optimal route for the single time period. This paper proposes a mathematical programming model for the vehicle routing problem for the parcel delivery in urban transportation with considering two time periods. Since the area of delivery is the same, the integration of demand of two time periods can reduce the total transportation costs.

Modelling a climate-weather change process effect on the resilience/safety of a critical infrastructure (CI) is presented. The model of the CI resilience/safety affected by dependences between its assets and subsystems and by outside climate-weather hazards is created. CI resilience/safety indices are defined and a way of their determination for the considered model is proposed. Procedures are used to the resilience/safety indices determination of the piping affected by the climate-weather change.

This paper studied the problem of parallel processing machine scheduling, taking both set up time and run-based preventive maintenance with reliability constraints into consideration. The objective is to minimize makespan. For this NP-hard problem, an Ant Colony Optimization (ACO) algorithm is proposed. The node selecting probability equation is set based on characteristics of this problem. The objective value obtained by the proposed algorithm is compared to that of the classical LPT rule through numerical experiments. The experiment results imply that the proposed ACO algorithm has better performance than the LPT rule.

In this era of big data, the conflict between data acquisition and privacy protection has attracted great attention. This paper proposes a Traffic Voting System (TVS) to help collect trip chain data and encourage travelers to share their information voluntarily. Travelers in the TVS will probably choose to share their travel information in exchange of less waiting time, as is proved by game theories. Trip chain data are collected by the TVS and this type of data is quite useful in traffic design and management. A comparison of TVS and other two similar systems is introduced in this paper. It is illustrated that the TVS is a traveler-centric system and is robust to deal with many complex situations in the traffic system.

Smart traffic service systems entail intelligent traffic analysis applications that enable highly functioning relationships between a range of users, including service consumers and service producers. This review paper envisions a systems architecture to empower a connected vehicle-to-X environment by integrating smart sensing and crowd sourcing technologies, large-scale cloud data analytics and computation, and predictive decision making and optimization into a coherent socio-technical configuration of people, operations and information through multimodal, real-time traffic monitoring, planning and control. Key technical challenges and research issues are discussed with respect to an illustrative case of roadway work zones.

For the problem that how to design the configuration of Reconfigurable Manufacturing System(RMS) with high efficiency during the RMS reconfiguration period, a configuration design method based on Living System Theory (LST) is proposed. Firstly, a multi-scale configuration design model of RMS is constructed, which analyzes the RMS configuration design process from the scale of manufacturing system, manufacturing cell and machine tool deeply. Secondly, the LST is used to decompose and represent the RMS multi-scale configuration design model, and a universal RMS multi-scale configuration design model is built based on the 20-critical subsystem of LST. During RMS configuration design process, the universal design model is reused, through the operations of adding, deleting or replacing, to deal with the order fluctuation and improve RMS reconfigure efficiency. Finally, a case is studied to elaborate the implementation of the presented method and validate the effectiveness and practicability.
