The unit cost is the cost incurred by a company to produce, store and sell one unit of a particular product. Unit costs include all fixed costs and all variable costs involved in production.
Method, program, and apparatus for estimating greenhouse gas emissions
The present invention provides a greenhouse gas emission estimation method, estimation program, and estimation device that can easily estimate greenhouse gas emissions linked to the final product and the cost associated with that final product. [Solution] The method for estimating greenhouse gas emissions includes the steps of: obtaining unit cost information that associates the unit cost of at least one type of resource material with at least one manufacturing facility used to process the product; obtaining yield information that associates the yield of the product with at least one manufacturing facility; obtaining combination information that associates a combination of greenhouse gas emissions and cost with the unit cost of at least one type of resource material; and estimating greenhouse gas emissions and cost when the product is processed at at least one manufacturing facility using the unit cost information, yield information and combination information.

Method and system for optimizing electronic spare parts configuration of a ship based on time-varying failure rate
This invention discloses a method and system for optimizing the configuration of ship electronic spare parts based on time-varying failure rate. The method includes: determining the ship's mission cycle, the configuration quantity of various electronic spare parts, and their unit cost; inputting the ship's mission cycle and the configuration quantity of various electronic spare parts into a spare parts demand model based on time-varying failure rate, and outputting the success probability of each type of electronic spare part; the spare parts demand model based on time-varying failure rate is constructed by combining the Weibull distribution function, the NHPP function, and the Poisson distribution function; constructing a bi-objective optimization configuration problem based on the success probability, configuration quantity, and unit cost; transforming the bi-objective optimization configuration problem into a single-objective optimization configuration problem using the IPM method; and solving the single-objective optimization configuration problem using the ALNS algorithm to obtain the globally optimal ship electronic spare parts configuration scheme. This invention achieves a better trade-off between reliability and cost, resulting in the optimal configuration scheme for ship electronic spare parts.
