Maximum quantity ordered

Another factor to discuss with the supplier is the maximum size of order that can be placed, what 3C calls QMAX. There may also be limitations on QMAX, such as lot sizes or supplier capacity. The best way to decrease the maximum lot size is to decrease the TBP. For example, reducing TBP from 30 days to 15 days would cut QMAX in half for SKUs. [Pg.420]


Typically, orders are simpler to explode than anonymous demands, because for an anonymous demand it might be required to define a distribution of the forecast quantities over the forecast interval only one quant, quants with equal quantities, due dates at the beginning or end or equally distributed. At this time it can be defined for each product if lot sizes, batch sizes, minimum quantities, maximum quantities of quants should be considered. The quantities are broken into predefined equal parts and then assembled until they meet the mentioned constraints. [Pg.84]

Water treatment of the intermediate. In order to recover the maximum quantity of ethyleneurea, it was necessary to treat the resinous polymeric intermediate with water. If the resin was reasonably fluid at 234—270° it was possible to recover ethyleneurea in high yield simply by passing superheated steam through it at these temperatures. [Pg.3]

The maximum quantity that is found is retained in memory and reported, along with the K-score and retention time, at the end of the experiment. The quantitative response of the PBM algorithm is linear for well over two orders of magnitude (Figure 8). [Pg.102]

As a general rule, in order to detect the maximum quantity of the protein components belonging to the pulp it is necessary to introduce protective agents into the extraction buffer, such as reducing substances, ascorbic acid, PVPP, etc., which minimize protein modifications and losses (Tattersall et al., 1997). [Pg.256]

Wifh this type of kiln sysfem, a higher quantity of excess air is required af fhe kiln exit in order to burn the additional fuel in fhe riser duct, but this then fosters the ideal conditions for alfernative and waste fuel use. The limit on heat in the riser duct is limited by several factors including duct geometry, system design, and fuel fype, and is generally limifed fo 25% of the total heat. This limit stems from the maximum quantity... [Pg.623]

The effects of added water on the rates of displacement of benzyl bromide and benzyl chloride with KCN salt in toluene catalyzed by 18-crown-6 were reported [145], It was observed that a small amount of water considerably increased the reaction rates compared to the anhydrous conditions and that the rate increased sharply to a maximum value in the presence of an optimum amount of added water. An important observation was that under anhydrous conditions, the reaction followed zero-order kinetics while in the presence of added water it followed first-order kinetics. It was suggested that the initial small amounts of added water coated the surface of the salt particle, which extracted the crown ether from the organic phase to form a new interfacial region called the omega (cd) phase. It was believed that the catalytic reaction took place mainly in the omega phase, since the quantity of added water corresponding to the maximum quantity of crown ether on the surface of the salt particles correlated well with the optimum quantity of added water. [Pg.266]

The order-promising process employed partitions the due date time horizon into three intervals fixed product, flexible product and flexible resource. For the fixed product interval, which spans from approximately the present time to two weeks into the future, resources, in the form of manufacturing orders (MO) are fixed. An MO specifies the production quantity for each product at each assembly line in each factory. That is, a fixed production schedule is set, which takes into account both production capacity availability and critical material availability. Having a fixed schedule stabilizes production dynamics in the near term and allows for the required materials to be set up and put in place. Any order commitments made for this time interval must fit within the fixed production schedule. In the flexible product interval, two kinds of resources, capacity and material, are considered. The capacity consists of both production capacity in different factories and transportation capacity from factories to sales subsidiaries. The production capacity is given daily at factory level in terms of machine-hour and manpower availability, while the transportation capacity is specified as weekly maximum quantity from factories to sales subsidiaries. The weekly availability of individual critical materials is aggregated into finished good level availability grouped based on the bill of material (BoM). Any order commitments made for this time interval must satisfy the capacity and material availability constraints. The flexible product interval spans from approximately two weeks to two months into the future. For the flexible resource interval, which covers due dates more than two months into the future, the only constraint considered is production capacity. This interval starts beyond the resource lead times so any resource commitments can be met. [Pg.452]

In one of its final assembly factories, Maxtor Corporation offers a component-level product. Hard Disk Drive (HDD), to its customers for further assembly of desktop PCs, high-end servers, consumer electronics products, network attached storage (NAS) server appliances, etc. (see www.maxtor.com). Maxtor has partnership-based B2B relationships with its customers. In this setting, customer orders are not given as specific order quantities and order due dates. Instead, only the total order quantity in each week is specified with permitted minimum and maximum quantity limits. In its order promising and fulfillment processes, Maxtor does not postpone customer orders to later weeks (i.e. no backorders), but it may deny customer orders subject to liability and/or penalties. While customer orders are promised weekly, the order fulfillment process is executed daily to provide accurate resource utilization and production schedules (see Ali, et al. 1998). [Pg.453]

In order to obtain minimum losses, the collimated light through the SLM has to illuminate the maximum quantity of pixels. As its intensity distribution has a Gaussian profile, it is sufficient that l/e beam bandwidth illuminates the SLM aperture. According to optical Gaussian laws, the following condition is reached ... [Pg.264]

Naturally, the maximum quantity of sulphur at which vulcanization proceeds according to zero order depends on the size of latex particles. [Pg.371]

A report on the continuous flash pyrolysis of biomass at atmospheric pressure to produce Hquids iadicates that pyrolysis temperatures must be optimized to maximize Hquid yields (36). It has been found that a sharp maximum ia the Hquid yields vs temperature curves exist and that the yields drop off sharply on both sides of this maximum. Pure ceUulose has been found to have an optimum temperature for Hquids at 500°C, while the wheat straw and wood species tested have optimum temperatures at 600°C and 500°C, respectively. Organic Hquid yields were of the order of 65 wt % of the dry biomass fed, but contained relatively large quantities of organic acids. [Pg.23]

The Phalaborwa complex ia the northeastern Transvaal is a complex volcanic orebody. Different sections are mined to recover magnetite, apatite, a copper concentrate, vermicuhte, and baddeleyite, Hsted in order of aimual quantities mined. The baddeleyite is contained in the foskorite ore zone at a zirconium oxide concentration of 0.2%, and at a lesser concentration in the carbonatite orebody. Although baddeleyite is recovered from the process tailings to meet market demand, the maximum output could be limited by the requirements for the magnetite and apatite. The baddeleyite concentrate contains ca 96% zirconium oxide with a hafnium content of 2% Hf/Zr + Hf. A comminuted, chemically beneficiated concentrate containing ca 99% zirconium oxide is produced also. [Pg.426]

Many other measures of solvent polarity have been developed. One of the most useful is based on shifts in the absorption spectrum of a reference dye. The positions of absorption bands are, in general, sensitive to solvent polarity because the electronic distribution, and therefore the polarity, of the excited state is different from that of the ground state. The shift in the absorption maximum reflects the effect of solvent on the energy gap between the ground-state and excited-state molecules. An empirical solvent polarity measure called y(30) is based on this concept. Some values of this measure for common solvents are given in Table 4.12 along with the dielectric constants for the solvents. It can be seen that there is a rather different order of polarity given by these two quantities. [Pg.239]

It should be noted that this is not necessarily the actual instantaneous maximum demand. The quantity measured on this meter is, of course, the maximum kW demand, but some forms of tariff are based on the maximum kVA demand in order to encourage power factor improvement (see below). [Pg.233]

In order to complete the discussion of methodical problems, we should mention two more methods of determining yield stress. Figure 6 shows that for plastic disperse systems with low-molecular dispersion medium, when a constant rate of deformation, Y = const., is given, the dependence x on time t passes through a maximum rm before a stationary value of shear stress ts is reached. We may assume that the value of the maximal shear stress xm is the maximum strength of the structure which must be destroyed so that the flow can occur. Here xm as well as ts do not depend or depend weakly on y, like Y. The difference between tm and xs takes into account the difference between maximum stress and yield stress. For filled polymer melts at low shear rates Tm Ts> i,e- fhese quantities can be identified with Y. [Pg.76]

For the exponential heating schedule (z = 1), the quantities Ed and T occur only when grouped in the term e = Ed/RT, and thus particularly simple expressions for the temperature Tm at the maximum desorption rate result, as was pointed out by Carter et al. (79) for the first-order kinetics and for the given quotient (kd/ax), Tm is exactly proportional to Ed for the second-order kinetics, the same applies as long as the initial coverage (Who/M8t) remains constant. For heating schedules other than the exponential one, the shift of Tm with increasing Ed is not exactly linear, due to the term T 1. [Pg.367]
