Financial flows are one of the three majors in a Supply Chain (SC). Ignoring financial flows, regardless of the quality of freight transport and information, could lead the organization to a state of bankruptcy, which is a situation directly resulting from a lack of control over financial inputs/outputs. This study proposes a multi-product mathematical model, which makes it possible to choose among suppliers, manufacturing sites, distribution centres, retailers, and transportation vehicles. The purpose of the model is to integrate physical and material dimensions to maximize net corporate profits through inbound and outbound financial flows; it involves payment mechanisms between the financial and physical flows through maximizing the cash flows of manufacturing sites and suppliers, as two conflicting objectives that must consider the reciprocal effects of their decisions. These objectives are calculated by subtracting costs from the revenue; this process, of course, will ultimately result in an optimization of the organization’s financial flow. To solve the proposed mathematical model, the study relies on two algorithms, namely Particle Swarm Optimization (PSO) and Imperialist Competition Algorithm (ICA). The sample under investigation is solved separately using the three algorithms, and results are then compared. The observations of the study reveal the better performance of PSO.

This study was aimed to analyze the supply chain distribution patterns of forest honey in the West Sumbawa through Sumbawa Forest Honey Network or Jaringan Madu Hutan Sumbawa (JMHS) using descriptive qualitative data. This study uses a supply chain distribution pattern approach based on the product, financial and information flow. In the product flow, honey is harvested by honey hunters in the forest and assembled to a group leader. Then, honey is handed over to JMHS and marketed at Rumah Madu” (Honey House). The forest honey harvest season in Sumbawa is between August-December. Honey hunters can harvest 15-20 liters of honey per hunter in one hunting day. In financial flow, we observed that the pricing of honey is decided by JMHS according to the market price and the harvest season. Honey price from the hunter is ranging from 60,000 - 75,000 IDR per 660 ml bottle. The purchasing price of honey by JMHS is 65,000-85.000 IDR per 660 ml bottle and after the packaging by JMHS, honey is marketed to the last consumers with a selling price of 110,000 IDR per 500 ml. The information flows in both directions. The group of honey hunters inform to JMHS about the locations of honey as well as the amount of harvested. In the JMHS side, they distribute information of the classification and quality of honey, provide the good harvest training and information on honey price to hunters.

The article deals with the theoretical and practical aspects of estimating accounting cash flows that directly generate cash flow, influence and are managed by various actors in the agribusiness and the entire agro-industrial environment. After all, in the country where the agribusiness is concentrated, there are a number of unresolved issues in the field of research of agro-industrial enterprises, which led to the need for generalization and development of accounting and analytical support for the assessment of data of agricultural enterprises within accounting approaches to analytical evaluation. An analytical evaluation of the effectiveness of financial flow management is provided, which assures the enterprises in the process of its strategic and current development. The processes of agribusiness financial flows management and decision-making processes that should ensure a smooth process are considered. The liquid cash flow characterizing the absolute value of cash is investigated. The conceptual model of accounting and analytical support of financial recovery was used, as well as the analysis of the results of the activity of agribusiness entities. The results of the study showed that financial flow as an accounting category is divided over time into a series of payments with positive and negative value – that is, cash flows and their equivalents. Therefore, it is necessary to have an adequate system of accounting information, which will allow to use all available resources with maximum efficiency for effective development of agribusiness in Ukraine. Therefore, analytical valuation is an integral part of today, because there is such a situation that many domestic enterprises are not able to provide effective cash flow management without properly organized accounting and analytical assessment of financial flows of agribusiness entities. Optimization of valuation will allow to determine the most effective forms and conditions of implementation of current operations, as well as rational directions of assets and profit placement. Only a comprehensive approach will allow to ensure transparency of the estimation process of financial flows of enterprises and will facilitate timely decision-making in the process of its activity. Key words: accounting and analytical support, agricultural enterprise, accounting approaches, cash flows, liquid cash flow, accounting system.

The article presents a special modification of the EOQ formula and its application to the accounting of the cargo capacity factor for the relevant procedures for optimizing deliveries when renting storage facilities. The specified development will allow managers to take into account the following process specifics in the format of a simulated supply chain when managing inventory. First of all, it will allow considering the most important factor of cargo capacity when optimizing stocks. Moreover, this formula will make it possible to find the optimal strategy for the supply of goods if, also, it is necessary to take into account the combined effect of several factors necessary for practice, which will undoubtedly affect decision-making procedures. Here we are talking about the need for additional consideration of the following essential attributes of the simulated cash flow of the supply chain: 1) time value of money; 2) deferral of payment of the cost of the order; 3) pre-agreed allowable delays in the receipt of revenue from goods sold. Developed analysis and optimization procedures have been implemented to models of this type that are interesting and important for a business. This — inventory management systems, the format of which is related to the special concept of efficient supply. We are talking about models where the presence of the specified delays for the outgoing cash flows allows you to pay for the order and the corresponding costs of the supply chain from the corresponding revenue on the re-order interval. Accordingly, the necessary and sufficient conditions are established based on which managers will be able to identify models of the specified type. The purpose of the article is to draw the attention of managers to real opportunities to improve the efficiency of inventory management systems by taking into account these factors for a simulated supply chain.

Water is a fundamental necessity of life. Yet water supply and distribution networks the world over are old and lacking in adequate maintenance. Consequently they often leak as much water as they deliver and provide an unacceptable quality of service to the customer. In certain parts of the world, water is available only for a few hours of the day. The solution is to build a mathematical model to simulate the operation of the real network in all of its key elements and apply it to optimise its operation. To be of value, the results of the model must be compared with field data. This process is known as calibration and is an essential element in the construction of an accurate model. This paper outlines the optimum approach to building and calibrating a mathematical model and how it can be applied to automatic calibration systems.
