The processes of optimization of the production plan according to certain criteria by modeling were investigated. Achieving effective results directly depends on the optimal production plan. The most important thing in determining the optimal production plan is the choice of modeling criteria. For the most part, the quality of decisions is characterized not by one but by many incomparable criteria. Therefore, it is necessary to make decisions based not on one but on many criteria. This so-called multi-objective optimization problem. For solving such problems is widely used mathematical methods. Mathematical approach can be used to solve problems in any particular activity as mathematics abstracted from specific features characteristic of a particular solution. Therefore, from the point of view of mathematics, the optimal result can be obtained with various established criteria, but from the economic point of view it is important to choose the ones that are of decisive importance. That is, their weight is important for the consumer when making a purchase decision, and for the manufacturer – in terms of production capabilities of certain types and results (production efficiency). The basis of the operation of any enterprise is a production program (production and sales plan). The main task of the production plan is to meet the needs of consumers in high-quality products, which are produced with the best use of resources, on the one hand, and the enterprise to get the maximum profit, on the other. With this in mind, a two-criteria optimization model that allows to make a production plan was proposed. The plan ensures that products are produced with the best use of available resources and at the same time ensures maximum quality of manufactured products and maximum profit from sales of these products. The solution of the problem with two objective functions and linear constraints is achieved by step-by-step solution of the proposed mathematical model of optimization of the production plan using the method of sequential restrictions. The simplex method was also used. An example shows an algorithm for solving the optimization problem.

The Cost

In this paper, a method is presented to combine financial data and financial statements for economic analysis, which consequently introduces a software application for determining the economic structure of a cement factory. This software converts nearly 300 items of raw data of a cement factory to almost 4 times more economic-analytic information. The software analyzes the quantity and quality of production activities in addition to the cost structure of the concerned cement factory. It provides more than 80 descriptive figures, which have been defined previously and are applied to illustrate the economic structure of the cement factory. The calculated tables and figures are able to guide decision makers of the cement factory with regard to inefficiencies, obstacles, and various problems in the factory. In the end, a set of policies for increasing production efficiency and reducing costs are expressed briefly, which can be considered as the primary plans to operationalize the analytical information of the software. It is worth to mention that the presented structure of the software has been designed for Abyek Cement Factory. However, it can be employed as a guiding project for other cement factories as well. In other words, the software can be rebuilt with consideration of their specific information by revising and adjusting the software structure to cover their specific features.

This study aims to study the sustainability of oil palm cultivation among smallholders in Lahad Datu on The Malaysian Sustainable Palm Oil (MSPO) Certification. A total of 300 oil palm smallholders in Lahad Datu, Sabah were interviewed using a set of questionnaires. The results of the analysis of this study show that oil palm smallholders have awareness of MSPO certification. Although they are aware of the need to have MSPO certification, they do not have such certification. Awareness of having MSPO certification can improve the quality of the environment while being able to increase the production efficiency and productivity of their oil palm plants. However, the management of the plantation by the Malaysian Palm Oil Board (MPOB) which is often undergoing changes and many application forms that need to be filled is the main reason why the oil palm smallholders do not get the MSPO certification. Strategic measures and awareness programs related to the importance of MSPO certification and related to oil palm cultivation need to be planned more widely by MPOB, in addition to introducing certification applications with a user-friendly, systematic, and innovative concept to attract more oil palm smallholders to obtain MSPO certification in line with the government’s efforts to optimize high-quality palm oil production in the future.

In two experiments, White Leghorn pullets kept in batteries were fed rations containing 0, 5, 10, 15, 20 or 30% raw faba beans (Vicia faba L.) for 336 days. The rations were designed to be isocaloric, isonitrogenous and to have equal levels of methionine plus cystine. The results obtained indicated that levels up to and including 20% faba beans in ration ssupplemented with methionine had no adverse effect on mortality, rate of egg production, efficiency of feed conversion or body weight. A level of 30% faba beans resulted in increased mortality, and decreased egg production and feed conversion in one experiment but had no effect in the other. Egg size tended to decrease as the level of faba beans in the ration increased, resulting in a considerable decrease in the percentage of "large size" eggs graded according to Canadian standards. There was an increase in interior quality of the eggs as measured by Haugh units as the level of faba beans used increased. Specific gravity of the eggs was not affected by use of faba beans in the rations.

Gracilaria sp is as eaweed with carbohydrate-rich wastes. Its symbiont, Brotia sp,is rich in calcium and protein. The effects of Gracilaria’s wastes (GW) as formulated feed supplement on carcass characteristics and production efficiency of local Indonesian ducks. Data were collected from 120 ducks fed either a basal dietor a fermented Gracilaria’s wastes supplemented diet (FGW). Treatment levels of FGW were 10%, 12.5%, and 15%. The highest level of meat antioxidant status was reached at 15% FGW, while the optimum level of FGW for decreasing the fat content was 12.5%. The best reduction in meat fat mass was at 15% FGW. Further more, duck feed with FGW resulted in lower average and normalized costs and increased income than observed with the basal diet. Thus, GW as a feed supplement effectively ameliorated the productivity and carcass quality of indigenous Indonesian ducks.
