Abstract

Sistem dinamik dapat dikembangkan dalam berbagai bidang kehidupan.Seperti dalam bidang ekonomi, salah satu sistem dinamik dalam bidang iniadalah model siklus bisnis. Ada beberapa model siklus bisnis, diantaranya modelIS-LM. Dalam penelitian ini akan dianalisa model siklus bisnis IS-LM dengan parametertime delay. Perbedaan antara keputusan investasi dengan implementasinyamenganjurkan untuk merumuskan model siklus bisnis IS-LM yang baru, yang memperlihatkanbahwa dinamika model sangat bergantung pada parameter time delay(waktu persiapan periode investasi). Dalam penelitian ini akan digunakan teoremabifurkasi Hopf untuk memprediksi kejadian dari limit cycle untuk parameter timedelay, yang menggambarkan siklus dari model IS-LM.

Abstract

The main goal of every company in business is the optimal profit. Challenges that often faced by companies in achieving maximum profit is the difficulty of combining every available resources of the company. The purpose of this study was to determine the maximum profit that can be obtained by Ls Garment using the simplex method and determine the impact of the changes that occur in the objective function coefficients and constants right side constraints to the optimal solution. Based on the results of the application method used, it was obtained maximum profit of Rp. 1.893.184,00 per day with the amount of Dress Payung, Celana Aladdin XL, Celana Aladdin XXL, Celana Aladdin ¾, Dress Kerut, and Daster Haji respectively are 34, 60, 68, 96, 26, and 26 pieces. Profit remain in optimal condition if the change of coefficients value at the objective function is less than or equal to the coefficient of the objective function at the initial model.

Abstract

Nadir Compromise Programming (NCP) is one of method that can be used to solve multiobjective problem using certain parameter. One of the problem that can be solved by these method is to get the optimum value of stock portfolio. The purpose of this study was to determine on what value of parameter among six values of parameter, NCP models effective in determining the optimum value of the stock portfolio. The data used in this research was secondary data in the form of daily data from the price of 6 types of stocks from October 2013 to October 2015. In this study, the optimum value of the stock portfolio was calculated by the the NCP model at 6 parameter values, i.e. 1, 10, 100 , 1000, 10000, and 100000. As a result of this study showed that the NCP model effective in determining the optimum value of the stock portfolio on parameter 1.
