Abstract

Knapsack Problem (KP) is known as one of combinatorial optimization problem that maximizes the amount of value (profit/ priority) of some of the items chosen to put in a sack or a bag without exceeding its capacity. KP has been applied in many fields: cargo loading, budget control, financial management and etc. In addition, KP is also included in NP-Hard problem. Several research have been conducted using some heuristic method to solve it. Some of these methods are Branch and Bound, Greedy Algorithms, Dynamic Programming, and Genetic Algorithms.However, when using GA, the feasibility of chromosome is one of critical issue. Most of optimization problem has constraint functions that will change the feasibility of solution. GA has some strategies to handle this case on the evaluation step. Evaluation not only calculates chromosome’s fitness value, but also handles the infeasible chromosomes presence. There’re rejecting strategies, repairing strategies, and penalty strategy.This paper develops a strategy GA approach with chromosome repairing strategy. In order to see the performance of the algorithm, we have done numerical experiment with several test problems taken on certain literature. In addition, this study will also give variations in GA parameter to determine the efficiency and effectiveness of the algorithm.

Abstract

Meet the patient's expectation is one of the requirements in health care quality. In order to achieve the healthcare quality, hospitals need to change the paradigm from drug oriented to patient orientation. The main problem in health care quality today is patients waiting a long time for service and it will increase the morbidity risk and socioeconomic cost. A solution to resolve long service time is to implement a queuing system that can predict the actual queue situation. This study aim is estimating the  waiting time of patients using Network Queue Jackson Method. We build a queuing model with 8 single servers and consists of 4 health care facilities, a registration, 5 consultation points for the patient, a pharmaceutical, and a cashier. In this method uses rules First Come First Serve where consumers can move from one workstation to another workstation before leaving the system. Through the Network Queue Jackson, each server or node can provide independent services that it possible to analyze each node separately.
