Solving Strategic and Tactical Optimization Problems in City Logistics Urban freight transport is a matter of increasing concern in the economic, commercial, social and environmental operations of our cities, due to the constantly increasing growth and urbanization of the civilization. An improved management of the traffic related to the freight transport can have a positive impact in many resp...

This paper describes the best first search strategy used by U-Plan (Mansell 1993a), a planning system that constructs quantitatively ranked plans given an incomplete description of an uncertain environment. U-Plan uses uncertain and incomplete evidence describing the environment, characterises it using a Dempster­ Shafer interval, and generates a set of possible world states. Plan construction ...

Home Health Care (HHC) services are a growing sector in the medical service business. These services are based on a delivery network in which patients are hospitalized at their homes and health care providers must deliver coordinated medical care to patients. The fact that patients and medical staff's homes are considered as a component of the delivery network creates a difference from typical ...

Home Health Care (HHC) services are based on a delivery network in which patients are hospitalized at their homes and health care providers must deliver coordinated medical care to patients. Demand for HHC services is rapidly growing and governments and health care providers face the challenge to make a set of complex decisions in a medical service business that has an important component of lo...

This paper describes The MITRE Corporation Center for Advanced Aviation System Development (CAASD) research towards simulation of advanced aviation concepts. Research activities are aimed toward improving tactical and strategic decision making methods in the near and long term. We describe how CAASD simulation capabilities assist in determining how to achieve our goals for improving tactical an...

This research extends agency theory by exploring the influence of varied, competing, principal interests on executive actions. Findings reveal that ownership of a firm by dedicated institutional investors, who hold concentrated portfolios over time, is positively associated with firm use of strategic competitive actions. Ownership by transient institutional investors, who hold broad portfolios ...

This paper investigates a novel approach to integrating tactical and strategical decision making and applies it to scheduling the operation of autonomous robot office couriers. In this approach the robot makes strategical (farsighted) decisions while it executes a plan using tactical (immediate) decisions and overwrites tactical decisions after strategical decisions have been reached (if necess...

The aim of the PPTS project (Pedagogical Platoon Training System) is to design and implement an evaluation environment for strategic and tactical skills, coupled to a network of full-scale simulators of the LECLERC tank. The three-level architecture adopted here is modelled on the levels of expertise, technical, tactic and strategic. The technical level is carried out by reactive agents, the mo...

—A hierarchical planning model was developed based on the needs of managers of the Menominee Tribal Forest in Wisconsin. The model utilizes a non-integer Model I goal programming formulation at the strategic level, and an integer Model II goal programming formulation at the tactical planning level. The strategic model is used first, to set general management direction for 150 years or more. The...

The analysis of capability requirements plays a very important role in military operations. It assists analysts to make decisions at strategic, operational and tactical levels. The analysis of capability requirements tends to be extremely expensive and time-consuming. Cutting-edge information technologies, such as red teaming, complex adaptive systems and agent based systems, can facilitate suc...
