This paper presents a real-time motion planning scheme for urban autonomous driving that will be deployed as a basis for cooperative maneuvers defined in the European project AutoNet2030. We use a path-velocity decomposition approach to separate the motion planning problem into a path planning problem and a velocity planning problem. The path planner first generates a collision-free piecewise l...

Program evaluation and review techniques (PERT) is an efficient tool for large project management. In actual project control decisions, PERT has successfully been applied to business management, industry production, project scheduling control, logistics support, etc. However, classical PERT requires a crisp duration time representation for each activity. This requirement is often difficult for ...

I this paper, we consider a class of two-stage stochastic optimization problems arising in the protection of vital arcs in a critical path network. A project is completed after a series of dependent tasks are all finished. We analyze a problem in which task finishing times are uncertain but can be insured a priori to mitigate potential delays. A decision maker must trade off costs incurred in i...

Abstract Critical thinking (CT) is widely regarded as an important competence to obtain in education. Students’ exposure problems and collaboration have been proven helpful promoting CT processes. These elements are present student-centered instructional environments such problem-based project-based learning (P(j)BL). Next CT, also higher-order (HOT) critical-analytic (CAT) contain that fostere...

large and complex infrastructure projects involve various risk factors and successful implementation of such project depends on effective management of the key risk factors. this paper reviews the literature to identify essential risk variables associated with infrastructure projects. base of these risk variables and case studies of same projects, a survey is conducted to isolate and assess the...

This report investigates the application of two Computer Vision techniques for characterizing critical regions in digital terrain maps: Skeletonization and Topographical Region Detection. The Navigation Path Planning problem involves nding the optimal path through a digital terrain Map and must minimize a cost function while satisfying the constraints of navigation. This process is computationa...

A procedure commonly used in Job Shop Scheduling Problem (JSSP) to evaluate the neighborhoods functions that use the non-deterministic algorithms is the calculation of the critical path in a digraph. This paper presents an experimental study of the cost of computation that exists when the calculation of the critical path in the solution for instances in which a JSSP of large size is involved. T...
