Demand Modeling with Overlapping Time Periods

Enhancing sustainability through resource efficiency in beef production systems using a sliding time window-based approach and frame scores

“…Similarly, the due time is also considered Gaussian but at least more than the ready time. Also, for analysis, market demand can be considered Gaussian with fixed mean and changing variance [ [40] , [41] , [42] ], but in practice, it can be determined using forecasting techniques. In Excel, the random number generation function under “Data analysis” was used to generate the Gaussian random data and afterwards rounded the values to the nearest multiples of tens (per pack size).…”

Reducing the Negative Effects of Seasonal Demand Fluctuations: A Proposal Based On Cost-Benefit Analysis

“…Therefore, in terms of companies, when the warehouses and storage activities are managed well, they can deliver competition advantage, they become the critical matters pointing out rising costs and inefficiency in the case of poor management. For this reason, issues related to storages and storage activities draw attention from both academicians and practitioners [14].…”

Modeling Lead Time Demand in Continuous Review Inventory Systems

“…In situations when demand distribution does not follow normal distribution, expressions presented above, generally are not appropriate for estimation of demand parameters for periods longer then unit time. More details and discussions about estimation of demand parameters for time periods longer then time unit can be found in [8]. In order to obtain more robust lead time demand parameters, we present our approach to lead time demand modeling below.…”

“…Using expressions (8) and (9) to find optimal values of and is not simple because each variable is dependent on each other. Since optimal values of and can not be estimated directly by analytical methods, it is possible to use iterative procedure.…”
