ConsumablesInventory
type: Class
subclass of: LogisticalTerms
acronym: CI
notes and explanation: The materials of which the quantity or quality are changed during the production such as a catalyst. (Consumables have been defined in detail in IEC 62264-1.)

ConsumedMaterial
type: Class
subclass of: LogisticalTerms
acronym: CM
notes and explanation: In the process industry (e.g. oil refining and chemicals), consumed material is usually used in the denominator to calculate the related KPIs. In some industrial processes, input can be less than the output. Many chemical and physical changes occur during production, and product yield has fluctuation and uncertainty. It is therefore difficult to calculate and measure the output.

application: The Critical machine capability index (Cmk) indicates the ability of a machine or a work mechanism to produce the specified quality. The evaluation should be executed if possible by exclusion of other process influences. The method will be used mainly with the approval from machines in combination with products
notes and explanation: Cmk is a critical characteristic value of a short time capability investigation. Usually the normal distribution will be the statistical method. The machine capability value is usually defined by customer requirements. Typical value is Cm > 1,66. The value can be used for characteristic with an upper and a lower specification limits. The Cmk can be calculated as (Cmku) index based on the lower specification limit and as the (Cmko) index based on the upper specification limit. The lower Cmk will be the relevant value of both calculations.

application: The Critical process capability index should indicate based on statistic methods as soon as possible if the production process will produce the product according to the committed quality specifications. The Critical process capability index (Cpk) is the relationship between the dispersion of a process and the upper or lower specification limit and its averages. The method compares the range between the upper or lower specification limit and its averages and the 3-sigma process dispersion. A process is usually called capable if the process capability index is > 1,33.
notes and explanation: The measurement has to be done in regular time steps or after defined quantity intervals with small samples (1-25). sˆ will be calculated based on a confidence factor from the standard deviation, depending on the sample inspection size. The x will be calculated as the average of the averages of all small samples. The Cpk can be calculated as (Cpku) index based on the lower specification limit and as the (Cpko) index based on the upper specification limit. The lower Cpk will be the relevant value of both calculations.

application: Production capacity and the load rate of equipment are important indicators in a manufacturing enterprise. The Equipment Load Rate KPI is calculated as: Equipment Load Rate = Produced Quantity (PQ) / Equipment Production Capacity Equipment production capacity is either “rated” or “maximum”, as follows: a) Maximum Equipment Production Capacity: the upper limit value of production demarcated before the equipment delivery. b) Rated Equipment Production Capacity: the upper limit value of production promised the stable operation of the equipment. The Equipment Load Rate KPI provides information about the ratio of produced quantity (PQ) in relation to the maximum equipment production capacity. It is an indicator to reflect the production state of equipment and production efficiency. It helps to reflect the technical performance and utilization of equipment and by researching the usage of equipment.
formula: Equipment load ratio = PQ / EPC
notes and explanation: The value of Equipment Load Rate impacts the production costs and, ultimately, profits.
rating max: 100%
rating min: 0%
rating trend: If the produced quantity is below the Rated Equipment Production Capacity, the higher, the better. It is possible to impact the security and reliability of equipment when the produced quantity is above the Rated Equipment Production Capacity. There is also a lower limit of Equipment Load Rate to some equipment, below which it cannot be produced.

EquipmentProductionCapacity

application: The Fall off ratio indicates the fall off quantity in each production operation step in relation to the produced quantity in the first operation. The KPI can be used in concatenated processes, where are mother products (e.g. motherboard) which will be produced in the first manufacturing step and will have scrap in the further operation steps. The mother products can be serialized in the first manufacturing step. The indicator has an influence on the planning quality (planned scrap) and on the production quality per manufacturing step as well as the material wastage.
formula: Fall off ratio = SQ / PQ of the first production order sequence
notes and explanation: This indicator is usable as online indicator for the worker level. In process industry, such as oil refining and chemical industry, usually use “consumed material” as denominator to calculate the related KPIs. It can be used "Finished Goods Ratio" (section 8.25) to calculate the quality.

application: The First pass yield (FPY) is a direct indicator for the process quality related to work place and product. The FPY considers the rate of yield over all production order operations. When the indicator increases then defect costs and material wastage will be reduced and the output improved.
formula: FPY = GP / IP
notes and explanation: For identifying the first pass it is necessary to label each single product unit with an identification number (serial number). The FPY designates the percentage of products, which fulfil the quality requirements in the first process run without reworks (good parts). The FPY stands in reciprocal relationship to the defect costs. If the FPY increases, then the defect costs will be less. This indicator is usable as online indicator for the worker level.

IntegratedGoodQuantity
type: Class
subclass of: LogisticalTerms
acronym: IGQ
notes and explanation: Products in the process industry are closely related to each other since partial amounts of a specific quantity of finished goods at a particular grade or quality can be converted to another product with a different grade or quality. For example, if the quality of a product has not reached a higher level “A”, it can be sold as a product with a lower quality level “B”. Then the ratio of products of level “B” raises as the ratio of products of level “A” declines. Therefore, KPIs are calculated from the view of all related products, such as the level “A” and level “B” products mentioned above. In this case, the KPI “Integrated Goods Ratio” is used instead of “Finished Goods Ratio” and “Integrated good quantity (IGQ)” is used instead of “Good quantity (GQ)” Since IGQ represents the quantity of all products during production, it is important to make sure that all products are measured in the same unit, or can be converted to the same unit. A list of conversion coefficients can be used to unify the measurement modes of different products.

application: The definition of indicators for inventory is quite important in the process industry where production is organized based on inventory. How long the product is stored may affect the quality and cost. The four types of inventory are described below. 1) Raw materials (RM): The materials that are changed into finished goods though the production. 2) Consumables (CI): The materials of which the quantity or quality is changed during the production, such as a catalyst. (Consumables have been defined in detail in IEC 62264-1.) 3) Crib and finished goods inventory (FGI): The stock point at the end of a routing is either a crib inventory location or finished goods inventory. Crib inventories are used to gather different parts within the plant before further processing or assembly. For instance, a routing to produce gear assemblies may be fed by several crib inventories containing gears, housings, crankshafts and so on. Finished goods inventory is where end items are held prior to shipping to the customer. 4) Work in process inventory (WIP): The inventory between the start and end points of a product routing is called Work in process (WIP). Since routing begin and end at stock points, WIP is the entire product between, but not including, the ending stock points. Although in colloquial use WIP often includes crib inventories, a distinction is made between crib inventory and WIP for clarification. Inventory Turns is defined as the ratio of the throughput (TH) to average inventory. It is commonly used to measure the efficiency of inventory, and represents the average number of times the inventory stock is replenished or turned over.
formula: Inventory turns = Throughput / average inventory
notes and explanation: Exactly which inventory is included depends on what is being measured. For instance, in a warehouse, all inventory is FGI, so turns are given by TH / FGI. In a plant, generally both WIP and FGI are considered, so turns are given by TH / (WIP+FGI). There are also other inventory turns in different departments, such as Raw Material Inventory Turns (TH/RMI), Consumables Inventory Turns (TH/CI), and so on. Attention needs to be paid to the boundary of the Inventory Turns in a Manufacturing Execution System. Usually, Inventory Turns in a Manufacturing Execution System only focuses on the inventory of WIP, while the Inventory Turns of RMI and FGI are usually the focus of an Enterprise Resource Planning system. It is essential to make sure that throughput and inventory are measured in the same unit.

application: The production process ratio is an index for the efficiency of the production. This indicator defines the relationship between the production time and the whole throughput time of a production order. When the production process ratio is low, then it means that the production orders include a lot of wait-time or idle periods instead of production time.
formula: Production process ratio = APT / AOET
rating max: > 100%
rating min: 0%
rating trend: By overlapping production order operations it is possible to get a result higher than 100%. Because the throughput time is related to production orders, the smallest entity will be a complete production order. The production time is the summary about all production time periods of all production order operations which are included in the selected production orders
rating trend: the higher, the better.
