Rancang Bangun Optimasi Kebutuhan Bahan Baku Menggunakan Algoritma Wagner-whitin

Lotting or purchasing raw materials is one step in Material Requirement Planning. Lotting technique that already known is the Wagner-Within algorithm. This algorithm is widely used because it provides optimal solutions for problem sizedeterministic dynamic reservation at a particular time period in which the needs of the entire period must be completed. It takes a application system of optimization planning raw material requirements using the Wagner-Whitin algorithm. The development of this process begins with building a power module of demand data using Arima method (1,1,1), then followed by forecasting modules of consumer demand for end product by using the multiplicative decomposition forecasting methods, and ends with the development of Materials Requirement Planning module (MRP I) using the Wagner-Whitin algorithm. The results of the test system with test data is the generation of data will form the same pattern that is likely up from week to week. Forecasting results have high accuracy registration of 99.48%, 99.64% and 99.68%. Wagner-Whitin algorithm always produces the combination of weeks. Result of the combination in the first week will produces the minimum cost for the entire week of production

Regime durability and foreign direct investment – growth nexus in developing countries

This study examines the role of regime durability in moderating the economic growtheffect of FDI inflows in 67 developing countries over the 1984-2016 period. The results based on the generalized method-of-moments panel estimation technique reveal that countries with durable regime benefit more from FDI inflows. The empirical results are robust to two alternative indicators of regime durability and FDI. The finding is consistent with the growing view that FDI spillovers depends on the capacity of host countries to absorb and internalize new technology associated with FDI inflows. In this respect, policymakers should weigh the cost of policies aimed at attracting FDI versus those that seek to improve regime durability
