Health IT evaluation studies have often been found to be of limited quality. To address this problem, several guidelines and frameworks have been developed as tools to support improvement of the quality of evaluation studies. In this contribution, we review available guidelines and then present the Good Evaluation Practice Guideline in Health Informatics (GEP-HI) in more detail. GEP-HI is a com...

Optimization models for expansion planning of power systems aim to determine capacities, investment timing, and location satisfy the demands while minimizing total cost. The have become complex in recent years reflect both regulations on conventional energy sources increasing penetration renewable (RES). This paper reviews basic concepts optimization systems. We first explain definition feature...

This paper introduces GEP(Gene Expression Programming) fundamental. Aimed at prediction of software failure sequence, an improved GEP(GEP based on Block Strategy, BS-GEP) is presented, in which the population is divided into several blocks according to the individual fitness of each generation and the genetic operators are reset differently in each block to guarantee the genetic diversity. The ...

The expansion of the transmission network will be a key enabler energy transition. However, high level technical detail involved in studies, where DCPF and consideration discrete investment are necessary, meant that it was accessible only to very specialized researchers. OpenTEPES changes picture by providing an open-access tool with full functionality. determines plans for new power facilities...

This paper presents an optimization model and its application to a generation expansion planning problem. The proposed model has a generalized network structure and is exploited effectively by Benders’ decomposition algorithm, where a master problem generates trial expansion plans and a set of subproblems compute production cost and system reliability for the trial plan. The applicability of ou...

presence of distributed generation (dg) in electric distribution systems provides an attractive new alternative in capacity expansion planning of these systems. in this paper a new model is developed for solving simultaneous placement of hv/mv substations and dg units as a static planning tool. this model aims to minimize fixed and variable costs of planning. constraints related to dgs, substat...

We discuss the energy generation expansion planning with environmental constraints, formulated as a nonsmooth convex constrained optimization problem. To solve such problems, methods suitable for constrained nonsmooth optimization need to be employed. We describe a recently developed approach, which applies the usual unconstrained bundle techniques to a dynamically changing “improvement functio...
