On-Line Sub-Optimal Obstacle Avoidance Zvi Shiller Mechanical and Aerospace Engineering University of California Los Angeles, CA 90095 Abstract This paper presents an on-line planner for sub-optimal obstacle avoidance. It generates near-shortest paths incrementally by avoiding obstacles optimally one at a time. In known environments, obstacles are avoided in an order determined by a global crit...

BACKGROUND Due to the rapidly increasing number of older people worldwide, the prevalence of frailty among older adults is expected to escalate in coming decades. It is crucial to recognize early onset symptoms to initiate specific preventive care. Therefore, early detection of frailty with appropriate screening instruments is needed. The aim of this study was to evaluate the underlying dimensi...

introduction: human resource plays a very important role in the success or failure of a company. the weakness in conclusion of criteria of model efqm (employee's criteria and results) using fahp method (fuzzy analytical hierarchy process) will be discussed here as iranian organizations are usually weak in their results field. method: the present study is an applied research. procedure of doing ...

This paper addresses the design of sustainable chemical supply chains (SCs) in the presence of uncertainty in the life cycle inventory associated with the network operation. The design task is mathematically formulated as a bi-criterion stochastic mixed-integer nonlinear program that simultaneously accounts for the maximization of the net present value (NPV) and the minimization of the environm...
