Automated inventory control Automation

Implementing automated product identification systems for inventory control. Bar code systems can code incoming products with information regarding composition, compatibility, storage location, and quantity. 

Scale tank systems or automatic batching systems are used in the margarine industry in order to meet today s requirements with regard to automation, accuracy, labor cost reduction, productivity, and inventory control (75, 82). 

Selected or installed process equipment and its affect on automation level Requirements with regard to level of operator interactions and labor Required degree of reporting within the plant in relation to quality control, inventory control, and accounting... 

Automated batching systems using scale tanks in margarine production offer a good solution toward higher productivity, better inventory control, accuracy in formulation, reduced labor requirement, and a consistent product. 

Automated inventory identification and management (automated ID) systems have been developed which greatly facilitate inventory control. Automated ID systems have created dramatic changes in the manage-... 

The local site inventories of control system spares are specified to be at least 10 percent of the installed base, with a minimum of two for each replaceable part. However, sites are maintaining their own supplies of additional noncertified control system spare parts and this is not well coordinated with the central spares control system at Rockwell Automation. The spares inventory control systems vary from site to site, and the committee noted that there is no comprehensive accounting of the inventory levels of spares, nor of the testing and certification status of spares, at some sites. This can result in program inefficiencies and cost penalties. 

An automated inventory control systems (AICS), which forms the backbone of the modem supply chain, is a software application used in a warehouse to monitor the quantity, location, and status of inventory. Modem AICS heavily relies upon barcodes, for automated data capture. 

Base layer control can be complex, based on the specific process requirements, with both feed-forward and feedback loops, sequence control, advanced inventory control, balancing control and various types of constraint and override control. The scope of the regulatory control of the Pearl GTL plant is large as approximately 9000 manipulated variables , i.e. control valves, motors, fin-fans, etc. are used to maintain stable operation at target. With regulatory control only (i.e. without other elements in the control and automation hierarchy) the plant should be able to operate smoothly and reject disturbances, although not necessarily in the most optimal fashion. 

Finally, materials reports may be directly interfaced with the contraaor s materials control sjj tem, which automates much of the requisitioning, tracking, field inventory control, and cost rqjorting. 

In the 1990s the major focus was on system validation, on assuring the quality control (QC) of the hardware and software that operated the manufacturing process, automated the laboratories, and controlled the inventory. As that validation process achieved mainstream acceptance and majority saturation it is appropriate to ask What next Where can we and the regulators most productively next turn our attention to maintain continuous quality improvement ... 

Preventive measures provide conditions where the incident is unlikely to happen, but its occurrence cannot be totally avoided. In this category, we find measures such as inventory reduction for critical substances, the choice of a continuous rather than a batch process leading to smaller reactor volumes, and a semi-batch rather than a full batch process providing additional means of reaction control. Process automation, safety maintenance plans, etc. are also preventative measures. The aim of these measures is to avoid triggering the incident and thus reducing its consequences. In the frame of mnaway risks, a mnaway remains theoretically possible, but due to process control, its severity is limited and the probability of occurrence reduced, such that it can be controlled before it leads to a critical situation. 

Provide a hst of all GxP-related computerized systems on site by name and application for business, management, information, and automation (equipment and process control) levels. Indicate the totahty of the inventory of computerized systems and indicate links with other sites/networks, etc. 

Under an annually renewed, systemwide contract with WGI, Rockwell Automation works with all of the incineration sites through surveys and visits to forecast requirements for control system spares (based on historical and forecast spares depletion rates), establish certified spares inventory levels for each site, repair or rebuild failed parts and components, and to special-build new parts and circuit cards as needed to keep maintenance inventories at a safe operational level. The Rockwell Automation support group, located in Cleveland, Ohio, also implemented a relatively simple soft-... 

Rockwell Automation also maintains a stockpile of spares at its facility in Memphis, Tennessee, equivalent to about 20 percent to 25 percent of the installed base to permit 24-hour turnaround for spares requests. The inventory of control system spares consists of about 75 percent of the installed part types. This includes a recent discovery of a cache of I/O parts at UMCDF, which will allow the inventory to provide for most part types. Any shortages are filled from Rockwell Automation s general spares supply that it uses for all its customers. Currently, about 90 percent of the CMA/WGI control system spares inventory have been retested and recertified.
