Special relationship between measurement conversions
Discrete manufacturers are also units of measurement conversion problems, such as tons to kilograms, boxes to together and so on, but the conversion between simple and complex.

Chemical enterprises in their production and operation process of the relationship between the measurement of conversion are extremely complex, storage and transportation of materials and processing, the conversion of its units of measurement depending on the company to the following situations:

A variety of conversion: the different stages in the production process using different units of measurement, and requires can be converted between the different units of measurement. Such as the time-gallon purchase, storage time t, when shipped in drums, the production time quarts (1.14 liters), ounces, and so time consuming. Each batch of materials conversion and material properties related to the relationship between conversion rates is more complex.

Performance relationship: Performance refers to the material composition, concentration, moisture content, the nutritional content of some food items and so on. Performance and logistics composition, concentration and other indicators have a close relationship between the weight or volume and cost.

Multi Packaging unit: packaging materials can be purchase, storage, production and sales during the morphogenesis of different packaging unit may be boxes, bottles, bundles, tank and container, etc.. Inventory needs of a large number of items in a variety of containers and packaging where possible combination of expression and inquiry, that the real-time enterprises need to know a lot of material packed separately in specific bottles, cans or boxes.

Costing the particularity
Chemical characteristics of the product determine the cost accounting complexity. Sulfuric acid plant, electro-chemical plants and other chemical companies have the particularity of their products need to develop specific costing methods. As some products need to convert 100% to calculate the concentration or purity of production and the standard cost; some need to consider co-products, by-products, etc.; while some inputs of raw materials need to be calculated based on product output of raw material inputs; some pipeline of products or other is not easy to measure materials, need to pre-set cost-sharing ratio. Also need to exercise strict control over the following cost elements:

Equipment investment in fixed assets, the proportion of the amount of up to 80 - 90% above, as soon as possible to recover investment in fixed assets will become the focus of chemical enterprise cost management;

Raw and auxiliary materials costs account for more than 70% of the total cost in the materials management, the need for a small amount of high cost of key raw materials or additives should be strictly controlled;

Power costs account for a large proportion of the total cost, accurate understanding of the energy levels of objects (departments, equipment) energy consumption (water, electricity, gas, etc.) data, the strengthening of energy management, energy conservation, improve the accuracy of cost accounting , and reduced product cost is very important.
