Inventory control

Keeping months of chemical inventory is often not possible, because of space limits, or desirable, because many chemicals degrade with time. However, running out of treatment chemicals is not a choice, and even running low is risky. Maintaining accurate chemical feed and records of historical chemical use is necessary for managing chemical inventory. To minimize costs, order full-load shipments. 

Chemical industries need various types of items for their safe, pollution-free operation. The process units and machineries need reliable spare parts for the smooth running. The wear and tear of various equipments is comparatively more in chemical industries than other industries due to corrosive nature of many chemicals and presence of fumes, dust, and gases. 

The various machineries for smooth conveying of sohd materials are helt, screw and bucket conveyors, hoists, overhead cranes, and fluid transf equipments such as pumps of various types, air blowers, and compressors. Many different types of processing reactor, filters, agitated vessels, condensers, gas absorbers, etc., are also required. 

They need spares such as belt fasteners, idler pulleys, buckets and chains, bearings and shafts, impellers, filter media, tower internals, heat transfer tubes, drive motors, etc. It is very important to always maintain adequate stock of all important components and spare parts because unsafe conditions can occur, environmental pollution may result, and production can get interrupted for want of these spares, e.g, 

it is necessary to correctly estimate the rate of consumption of various items at maximum production capacity instead of the rated production capacity of the plant. Some typical consumables and spares are catalysts, gaskets, special pipes. 

This can be done by properly recording the replacements of spares carried out and other items consumed over 6 months to 1 year. The figures for stock levels could be higher than the figures recommended by vendors and can increase the cost of inventory. However, it is better to be on the safer side. 

The implementation and maintenance of a POCT service require that a supply of devices be maintained at all times and a formal program for doing so employed. The key points 

The complexity in the maintenance, of reusable devices will vary from system to system, but clear guidelines wiU be available from the manufacturer and should be adhered to rigorously. Issues that usually require particular vigilance include expiration dates, bio-contamination, electrical 

The documentation of all aspects of a POCT service has been a major issue for many years, compounded by the fact that often the storage of data in laboratory and hospital information systems has been limited and often inconsistent. Thus it is critically important to keep an accurate record of the test request, the result, and the action taken as an absolute minimum. Some of the issues concerning documentation are now being resolved with the advent of the patient electronic record, electronic requesting, and better connectivity of POCT instrumentation to information systems and the patient record (see earlier discussion).

Servo Gauge. Servo gauges are high accuracy, electromechanical devices that are used on inventory control appHcations where accountabiUty is mandated for custody transfer of Hquids. The large, million barrel, bulk terminal vessels are where these devices originally found a niche. 

Use of Results. Sales analysis data are used ia many ways by company management. The results are most useful ia production planning, particularly if grade differences appear to be ia the offing, and ia assuting that adequate suppHes are available for sales. Inventory control, raw material procurement, technical service requirements, and trends ia accounts receivable are beneficiaries of good sales analyses. 

Economy of time and resources dictate using the smallest sized faciHty possible to assure that projected larger scale performance is within tolerable levels of risk and uncertainty. Minimum sizes of such laboratory and pilot units often are set by operabiHty factors not directly involving internal reactor features. These include feed and product transfer line diameters, inventory control in feed and product separation systems, and preheat and temperature maintenance requirements. Most of these extraneous factors favor large units. Large industrial plants can be operated with high service factors for years, whereas it is not unusual for pilot units to operate at sustained conditions for only days or even hours. 

Colorants can be added to plastics by several methods. The incorporation of the colorant often is a balance between a particular end property requirement and inventory control. The typical forms in which colorants are added are raw colorant, dispersed colorant, dry concentrate, and Hquid concentrate. Furthermore, resins can be purchased that have the colorants dispersed in them, thus the resin is precolored.

The principles outlined in the standard can be applied to any creative activity and while the standard primarily addresses the design of automotive products for onward sale to customers, the principles can be applied to internal systems such as an information technology system, an inventory control system, and even the quality system. 

An effective maintenance system depends upon it being adequately resourced. Maintenance resources include people with appropriate skills, replacement parts and materials, access to support from OEMs when needed, and the funds to purchase this material. If the equipment is no longer supported by the OEM, then you may need to cannibalize old machines or manufacture the parts yourself. This can be a problem since you may not have a new part from which to take measurements. At some point you need to decide whether it is more economical to maintain the old equipment than to buy new. Your inventory control system needs to account for equipment spares and to adjust spares holding based on usage. 

There are, however, issues other than quality which will govern the control of items in stock. Inventory control is a vital part of any business. Stock ties up capital, so the less stock that is held the more capital the firm has available to apply to producing output. 

A common solution, which satisfies both the inventory control and quality control, is to institute a stock requisition system. Authorization of requisitions may be given by a person s supervisor or can be provided via a work order. If someone has been authorized to carry out a particular job, this should authorize the person to requisition the items needed. Again for inventory control reasons, you may wish to impose a limit on such authority requiring the person to seek higher authority for items above a certain value. 

This report addresses ammonia plant shutdowns over the listed time period in 40 countries. It provides a basis for comparing plant performance area by area leading to better control of reliability efforts while reducing maintenance and unplanned shutdown costs. Data are presented for shutdowns due to power, equipment, instrumentation, feedstock and product inventory control. 

Our next example concerns the Poisson process, which plays a central role in a variety of problems such as waiting lines, inventory control, electrical noise, the firing of neurons, and radioactive decay. We will discuss the application of the Poisson process to the study of certain kinds of electrical noise in a later section. 

This system includes measures and activities to control finished products, components, including water or gases that are incorporated into the product, containers and closures. It includes validation of computerised inventory control processes, drug storage, distribution controls, and records.

Improved inventory control and reduced inventory costs. 

Flow control is usually associated with inventory control in a storage tank or other equipment. There must be a reservoir to take up the changes in flow-rate. 

Another important feature of the case study scenario and the resulting cost model is inventory control. High seasonality effects and long campaign durations necessitate considerable build-up of stocks. To avoid an unbalanced build-up of stock, soft constraints for safety stock and maximum stock levels are used. To achieve an even better inventory leveling across products and locations, piece-wise linear cost functions for falling below safety stock as well as for exceeding maximum stock levels are employed.
