decisions relating to most irrigation-planning problems need to be made in the face of hydrologic uncertainties, which make the irrigation-planning problem more complex. the uncertainties can be tackled by formulating the problem as fuzzy linear programming (flp). in the present study, single objective fuzzy linear programming (soflp) irrigation planning model was formulated for deriving the op...

The paper describes an experiment of answer set planning in biochemical pathway planning. The focus is on large planning problem instances. It is shown that well-known planning techniques, such as planning graph analysis, landmarks recognition, and planning using landmarks are useful in answer set planning and can be easily incorporated in an answer set planning system.

The optimal product design problem, where the ‘‘best’’ mix of product features are formulated into an ideal offering, is formulated using ant colony optimization (ACO). Here, algorithms based on the behavior of social insects are applied to a consumer decision model designed to guide new product decisions and to allow planning and evaluation of product offering scenarios. ACO heuristics are eff...

Product mix problem (PMP) is one of the most important and complicated problems in production systems. Different approaches have been applied to solve this problem, among them, theory of constraints (TOC) has been widely considered since 1990s. This paper develops a distinguished algorithm to solve product mix prob-lems that is efficient both in single and multi-bottleneck problems. At first, t...

Medicare paid hospitals a higher amount per admission in 1984 than had been planned because the case-mix index (CMI), which reflects the proportion of patients in high-weighted DRG's versus low-weighted ones, increased more than had been projected. This study estimated the degree to which the increase in the CMI from 1981 reflected medical practice changes, the aging of the Medicare inpatient p...

Background: There are limited case-mix classification systems for primary care settings which are applicable when considering the optimal clinical skill mix to provide services. Aim: To develop a case-mix classification system (CMCS) and test its impact on analyses of patient outcomes by clinician type, using example data from physician associates’ (PAs) and GPs’ consultations with same-day app...

Primary health care (PHC) represents the first contact between the health care system and the citizens. Over the past years it has been noticed that demand for primary care is increasing. The population is growing older and the prevalence of chronic conditions is increasing. However, the resources provided by the Portuguese National Health System (NHS) are not enough to satisfy the demand, bein...

This paper addresses the problem of production planning in a divergent lumber production environment. It aims at analyzing operational performance changes by introducing pull production flow control mechanisms into the production part of the lumber supply chain. An agent-based simulation evaluation is performed using an experimentation platform based on a distributed advanced planning and sched...
