摘要:
The invention provides a polyester produced in the presence of a polycondensation catalyst comprising at least one compound selected from a group consisting of aluminum compounds and at least one compound selected from a group consisting of phosphorus compounds and being excellent in color tone, thermal stability, and transparency and improved in terms of insoluble particles. Particularly, the invention provides a polyester in which the content of an aluminum containing insoluble particles in the polyester is 3500 ppm or lower and a polyester which has a haze value of 2% or lower when being formed into a monoaxially oriented film. The aluminum catalyst for attaining these characteristics and properties may be polyester polymerization catalyst obtained by mixing an aluminum compound and a phosphorus compound in a solvent and has specified spectral characteristics in the side measurement of 31P-NMR spectrum and 27Al-NMR spectrum.

This invention provides a polyester and a polyester molded product, which, while maintaining color tone, transparency, and thermal stability, can realize a high polycondensation rate, are less likely to cause the production of polycondensation catalyst-derived undesired materials, and can simultaneously meet both quality and cost effectiveness requirements, which can exhibit the characteristic features, for example, in the fields of ultrafine fibers, high transparent films for optical use, or ultrahigh transparent molded products. These advantages can be realized by using, in the production of a polyester in the presence of an aluminum compound-containing polyester polycondensation catalyst, an aluminum compound having an absorbance of not more than 0.0132 as measured in the form of an aqueous aluminum compound solution, prepared by dissolving the aluminum compound in pure water to give a concentration of 2.7 g/liter in terms of the amount of aluminum element, under conditions of cell length 1 cm and wavelength 680 nm.

The invention displays multiple inventory period combinations, as multiple multi-base inventory deployment proposals having assessed values for items such as cash flow and inventory value, each of said assessed values being within a range entered by an inventory deployment decision-maker. For each product included in request information, the invention finds a minimum period (the total lead time from when a given item leaves the applicable warehouse until the item reaches the base that sells the applicable product) and a maximum period (the total lead time needed for all component parts configuring the item to reach the warehouse, added to the minimum period), for each item configuring said product and each warehouse base. The invention computes product-specific inventory period combination information for each warehouse base, and creates inventory period combination information by combining said product-specific inventory period combination information for each product type. The invention performs an inventory management calculation for the inventory period combination information, computes the value of an assessment index, and compares said value to the maximum value thereof. The invention selects an inventory period combination having an assessment index value within a permitted range, as a candidate display proposal. For the candidate display proposal, the invention computes a display evaluation value for each display proposal evaluation item by multiplying a display evaluation coefficient by an inventory value.

A production plan enabling suppression of occurrence of excess stock is made. A shipping request representing the requested amount of shipping for each shipping request week is received. Among the shipping weeks of the shipping requests, the furthest future shipping request week is handled as the furthest future shipping week, and the amounts of shipping of shipping weeks near the present time are determined sequentially from the amount of shipping of the furthest future shipping week. For the shipping requests after the shipping week n for which the amount of shipping is to be set, the order setting time which is the time of period till the products are delivered to the shipping destination is determined. The allocation order, 1, 2, . . . is determined for each of the shipping requests of the unset shipping so that the longer the order setting time is, the higher the order of allocating shipping request is. In the allocation order, the requested amounts of shipping for the shipping requests of the unset shipping are allocated sequentially to the shipping week n until the amounts of shipping reach the production capability (1300) of the product. When the amounts of shipping exceed the production capability, the excess over the production capability is handled as the amount of unset shipping, and the amount is allocated to the shipping week (n−1) and so forth before the shipping week n.

An issue to be settled by the present invention is to define a simulation model in accordance with the structure of a causal relation easy to be understood by human and to shorten greatly a simulation program development period. A simulation program is automatically generated by extracting, as nodes, specific items such as phenomenon, events and targets of constituent elements of economy, society or the like regarded as a system, coupling the nodes with arcs to define the structure of the causal relation, and defining a variable necessary for calculating metrics and a calculation formula therefor, relative to a simulation model inheriting the defined structure.

An analysis apparatus includes a needs relation definition unit to receive input of relation among needs for a product, worth to satisfy the needs and values of selection items for selecting the worth through an input unit and a needs estimation unit to prepare a questionnaire which receives selection of selection order for combination of inputted needs and selection of values for judging to be satisfactory and dissatisfactory for inputted worth and calculate strength of the needs from totalized result of the questionnaire.

Provided is a system which supports appropriate price setting so that a value for a provider in a transaction and a value for a customer reach an agreement. A price setting system stores a provider cost Cp and a return Rc obtained by a customer to calculate a transaction value Vp for the provider and a transaction value Vc for the customer in accordance with an evaluation index (benefit-based, price ratio-based, or ROI-based). Then, the price setting system outputs information that supports the setting of a price P satisfying Vp>0 and Vc>0.
摘要:
A solution design method and system for designing solution specification and estimating a period and a price speedily on the basis of customer needs, the budget of solution, the target period of implementation of solution, etc. The customer budget or period is used as a constraint so that a gap between solution specification as the customer's request and solution specification in consideration of the constraint is clarified so that tasks and resources taking charge of each other are clarified to satisfy the quality required by the customer. Individual resource conditions are set in consideration of priority of each solution task. The settings themselves can be changed arbitrarily in accordance with the customer needs. The definition of resource ranks in each customer can be executed again on the prerequisite of the customer's request or the like. While the prerequisite is clarified, design of solution specification and estimation can be performed simultaneously without assignment of resources.

The shipping planning system stores price/quantity relationship data for products in advance, calculates additional variable cost for shipping quantity for each product based on available resource and inventory, procured resource amount, procurement lead time, and available facility capability, evaluates relative profit subtracting opportunity loss of other products which shares the resources from a margin profit of the product using the additional variable cost, and determines the product to be shipped which makes the relative profits positive, and a shipping quantity and a price of the product using the price/quantity relationship data.
