Abstract

Economic Production Quantity (EPQ) used to determined policy and oversee inventory levels. This article discussed on EPQ models for  planed of product with partial backordered and its component. The final product is assummed have m component and coordinated planning used to coordinate component of product and final product which is the components used for basic EPQ models and for final product planned using partial backorder EPQ. Numerical simulation given based  data on UD. Adi Mulya.

Abstract

Economic Order Quantity model with partial backorder system and incremental discount is an integration of several model of inventory optimation, they were Economic Order Quantity optimation model, Economic Order Quantity optimation model with partial backorder system and Economic Order Quantity optimation model with incremental discount. Beside the discounts are given by supplier, in this model there were two stockout conditions, where the consumers disposed to wait until the order came and consumers did not disposed to wait until the order came.

Abstract

Not fully fuzzylinear programming problem have two shapes of objecyive function. that is triangular fuzzy number and trapezoidal fuzzy number. The decision variables and constants right segment only has a triangular fuzzy number. Partial order method can be used to solve not fully fuzzy linear programming problem with decision variables and constants right segment are triangular fuzzy number. The crisp optimal objective function value generated from the partial order method.

Abstract

tability the discrete chaotic systems is interesting to be discussed, given that chaos is closely related to random and irregular state. Stability of discrete chaotic system can be obtained using impulsive control law and applying Lyapunov stability theory. So it can show sufficient conditions for the design of impulsive controllers and  globally exponentially set-stable can be reached. Based on the results of the impulsive  control, it is seen that the behavior of chaos in a discrete chaos system which originally the trajectory are irregular, can be control and become stable, and there is a globally exponentially attracting set earned in the system. The numerical simulation on the discrete chaotic system is presented to illustrate the effectiveness of the obtained results from control impulsive.

Abstract

Liver is an important organ for humans. One of the liver disease that received both national and international attention is caused by Hepatitis B. Hepatitis B has the first rank in term of number and spread which it is transmitted through blood or body fluids. In this paper, we discussthe mathematical model in facing Hepatitis B spread.Firstly, we formulate the dynamics of Hepatitis B spread by dividing the population into five classes namely susceptible, exposed, infected, carrier and recovered subpopulation. By using the basic reproduction number value,we analyze the spread of Hepatitis B. From the result, the increasing of the recover rate for infected and carrier subpopulation and the decreasing of infected individu are the best strategy in order to make the rate of Hepatitis B spread is decreasing.

Abstract

In this paper we propose diophantine equations with the form  and . These equations has integer solutions which can form Fibonacci numbers and Lucas numbers. Integer solutions of the Diophantine equations in the form of Fibonacci number and Lucas number are determined by using recursive formula, Binet’s Formula, and the most important is identity of Fibonacci numbers and Lucas numbers.

Abstract

In this paper we study Henstock-Bochner and Henstock-Dunford integral on [a,b]. We discuss some properties of  the integrable. For every function which Henstock-Bochner integrable then it is Hentsock-Dunford integrable. The contrary is not true. Further more, let for any  and collection  is Henstock-equi-integrable. We will show that function   is Henstock-Bochner  integrable on   if only if  it is Henstock-Dunford integrable on .

Abstract

Given graph  with set of vertex  and set of edge E. Set  subset of  is called domination set if every point in  is adjacent with at least one point in  in graph . The minimum cardinality of all set of domination graph  is called domination number. Let  be a subset of , set  is called a neighborhood set if  with   induced subgraph  of . The minimum cardinality of all the neighborhood set of graph  is called the neighborhood number. There are several types of neighborhood domination number depending on the parameters. In this paper we examine the transversal neighborhood domination number and global neighborhood domination number in complete graph and complete bipartite graph.
