Inventory subsystem

The sample index file is keyed by the sample or bottle nvim-ber. This number is cross-referenced to the accession number so that a given Scunple may be attached to a specific structure. The sequence permits the chemistry subsystem direct access to either the biology or the inventory subsystem euid provides for direct access of the structures for reports by the inventory and/or biology subsystems. The scinple index file also contains some administrative information cUaout each Scunple such as the source the method by which the sample was obtained (e.g. gift, purchased, etc.), whether this sample is the original submission or a duplicate, discreet (i.e., proprietary) or open. 

While either the Biology or Inventory subsystems may be searched independently, in practice this is seldom done. More often, information from more than one system must be found in... 

Evidence of sufficient control of these issues should be demonstrated in the validation documentation. Compliance must be integrated using a formal methodology and an appropriate system life-cycle approach that is clearly identified in the user requirements phase for any new computerized systems. The priority for validation activities can be established by analyzing the control scheme system and subsystem inventory for the criticality, validation stams, software category, and system type. This analysis aids validation planning and prioritization. 

Step 1 Evaluate the impact of the control scheme and its subsystem on the product quality. This involves the creation of a system inventory or register. The register may be in the form of a validated, controlled, and approved spreadsheet or database. Systems that are deemed to have No Impact on product quality would normally be dealt with by applying Good Engineering Practices. 

The inventory analysis is a technical process of collecting data, in order to quantify the inputs and outputs of the system. Energy and raw materials consumed, emissions to air, water, soil and solid waste produced by the system are calculated for the entire life cycle of the product or service. To make this analysis easier, the system under study is split into several subsystems and unit processes, and the data obtained are grouped in different categories in a LCI table. 

Communications subsystems, which enable information flow between the various DCS subsystems as well as to other computerized systems such as laboratory information management systems (LIMS) plant inventory management and scheduling systems such as MRP II plant maintenance systems and business systems. 

The inventory of impurities is a plantwide control problem, because it involves both the reaction and separation subsystems through recycles. Ideally, the inventory of each component should be traced from the source to its final destination. Recent systematic studies on the dynamics and control of the recycle systems have been started, as described in the Chapter 13. Luyben and Tyreus (1998) proposed a ten steps plantwide control design procedure (section 13.7). The step 7 consists of Checking component balances, identify how chemical components enter, leave, and are generated or consumed in the process. At this stage it is necessary to find the specific mechanism or control loop to guarantee that there will be no uncontrollable build-up of any chemical component within the process . 

The second subsystem includes three motor-driven pumps of 10 m /h capacity and of 3.0 MPa pressure head. Its water inventory is 50 m. Each system has two channels. A special system for recirculation of water from the condensate collectors back into the reactor is provided using glandless motor pumps. A special structure excludes loss of coolant and ensures long-term passive heat removal from the core and reactor vessel during beyond design base accidents.

This section describes a proposed methodology to evaluate the environmental impact of a chemical industrial process chain in the most accurate way possible. It includes a procedure to compute the LCI based on the concept of eco-vectors [Sonneman et al., 2000], Each process stream (feed, product, intermediate or waste) has an associated eco-vector whose elements are expressed as Environmental Loads (EL, e.g. SO2, NOJ per functional unit (ton of main product). All input eco-vectors, corresponding to material or energy streams, have to be distributed among the output streams of the process (or subsystem). In this sense, a balance of each EL of the eco-vector can be stated similarly to the mass-balance (input = output + generation ). This is the reason why all output streams are labelled as products or emissions. The eco-vector has negative elements for the pollutants contained in streams that are emissions and/or waste. Figure 1 illustrates these ideas for an example of a chain of three processes that produces a unique product. The proposed procedure associates inventory data with specific environmental impacts and helps to understand the effect of those impacts in human health, natural resources and the ecosystem. 

For the functional design of our cluster we have considered plants and processes from the entire production chain, ranging from fossil and renewable fuels to methanol derivatives, such as fiber board plants that make use of formaldehyde. In addition, the cluster includes industries that process or use by-products such as hydrogen and platinum. The cluster comprises five main functional areas. For each of these functional areas we have made an inventory of possible interactions, flows and subsystems ... 

In GE BWR/5 and BWR/6 plants, the LPCI (low pressure coolant injection) subsystem constitutes a portion of the emergency core cooling system. The LPCI restores and, if required, maintains the coolant inventory in the RPV after a loss-of-coolant accident by injecting water directly inside the core shroud. The LPCI coupling is a sleeve connection which accommodates the thermal expansion mismatch between the RPV and the core shroud as shown in Figure 2-14. 

An LRU indicates the operations or maintenance level at which a system element can be replaced. An LRU is typically a subsystem that can be replaced on the operational line from a spare that is in inventory. It is... 

Inventory Retrieval Subsystem. The inventory retrieval subsystem is an indexed sequential file containing information pertinent to the physical samples. It currently contains 433 thousand records and occupies 5 disk packs of 37 million characters each. The file is maintained in sample number sequence. When a sample is received it is assigned the next availaible sample number and all available data (i.e., date of receipt, source, amount, condition of receipt, shelf location, chemical and physical properties, etc.) are entered into the record. All transactions involving that sample (shipments to testing Icib-oratories, removal from inventory, etc.) and the date of the transactions are also entered into record. The data fields for this file are also predefined in a data name dictionary for searching.
