This paper considers a dairy industry problem on integrated planning and scheduling of set yoghurt production. A mixed integer linear programming formulation is introduced to integrate tactical and operational decisions and a heuristic approach is proposed to decompose time buckets of the decisions. The decomposition heuristic improves computational efficiency by solving big bucket planning and...

backgroundfor using of complementary and alternative medicine methods (cam) in the leukemia pediatrics than other types of cancer, we have two great challenges; first challenge is their safety and risks and second challenge is study gaps in this field. regarding to these challenges, this study is a narrative review of some cam methods in the leukemia pediatrics from the perspective of their saf...

background and purpose: inappropriate complementary feeding practices are one of the causes of malnutrition worldwide. this study was aimed to determine the complementary feeding practices according to world health organization recommendation in sari, iran. materials and methods: this cross-sectional study on complementary feeding practices assayed the different aspect of infant feeding based o...

a theorem was recently introduced to establish a relationship betweengoal programming and fuzzy programming for vectormaximum problems.in this short note it is shown that the relationship does not exist underall circumstances. the necessary correction is proposed.

Community, local, and regional food systems (CLRFS) programming reflects important issues priorities that intersect with Extension the sustainability of our system. CLRFS in Extension, however, is still developing slowly while movements grow nationally. This article describes a model complementary process for conducting listening sessions professionals community leaders to develop enhance addre...

Linear Complementary Dual codes (LCD) are binary linear codes that meet their dual trivially. We construct LCD codes using orthogonal matrices, self-dual codes, combinatorial designs and Gray map from codes over the family of rings Rk. We give a linear programming bound on the largest size of an LCD code of given length and minimum distance. We make a table of lower bounds for this combinatoria...

We discuss a portfolio optimization problem occurring in the energy market. Energy distributing public services have to decide how much of the requested energy demand has to be produced in their own power plant, and which complementary amount has to be bought from the spot market and from load following contracts. This problem is formulated as a mixed-integer linear programming problem and impl...

We consider the natural generalizations of packing and covering polyhedra in infinite dimensions, and study issues related to duality and integrality of extreme points for these sets. Using appropriate finite truncations we give conditions under which complementary slackness holds for primal/dual pairs of the infinite linear programming problems associated with infinite packing and covering pol...

Here we present an implementation of Primal-Dual Affine scaling method to solve linear optimisation problem on GPU based systems. Strategies to convert the system generated by complementary slackness theorem into a symmetric system are given. A new CUDA friendly technique to solve the resulting symmetric positive definite subsystem is also developed. Various strategies to reduce the memory tran...

This paper is devoted to consider the notions of complementary problem (CP) and set-valued complementary problem (SVCP). The set-valued complementary problem is compared with the classical single-valued complementary problem. Also, the solution set of the set-valued complementary problem is characterized. Our results illustrated by some examples. This paper is devoted to co...
