The book-to-bill ratio, also known as the BB ratio or BO/BI ratio, [1] is the ratio of orders received to the amount billed for a specific period, usually one month or one quarter. It is widely used in the technology sector and especially in the semiconductor industry, where the semiconductor manufacturing equipment (SME) book-to-bill ratio is ...
Demand for items from inventory is continuous and at a constant rate; Production runs to replenish inventory are made at regular intervals; During a production run, the production of items is continuous and at a constant rate; Production set-up/ordering cost is fixed (independent of quantity produced) The lead time is fixed
The equation below (in Cobb–Douglas form) is often used to represent total output (Y) as a function of total-factor productivity (A), capital input (K), labour input (L), and the two inputs' respective shares of output (α and β are the share of contribution for K and L respectively). As usual for equations of this form, an increase in ...
A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. The chart is named for the Pareto principle , which, in turn, derives its name from Vilfredo Pareto , a noted Italian economist.
The ratio between in place and recoverable volumes is known as the recovery factor (RF), which is determined by a combination of subsurface geology and the technology applied to extraction. [13] When reporting oil & gas volumes, in order to avoid confusion, it should be clarified whether they are in place or recoverable volumes.
Role of Production Planning in the Production Cycle. Production planning is the planning of production and manufacturing modules in a company or industry. It utilizes the resource allocation of activities of employees, materials and production capacity, in order to serve different customers. [1]
There are two types of costs: those which increase with the batch size such as working capital investment in materials and labor, cost of handling and storing materials, insurance and tax charges, interest on capital investment, etc., and those which decrease with the batch size such as cost (per unit) of setting up machines, cost of preparing ...
In operations management and industrial engineering, production flow analysis refers to methods which share the following characteristics: Classification of machines; Technological cycles information control; Generating a binary product-machines matrix (1 if a given product requires processing in a given machine, 0 otherwise)
