Schneck, Christie. "Between Words: Popular Culture and the Rise of Print in Seventeenth Century England." Master's thesis, University of Central Florida, 2012. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/5485.
Full textAbstract:
Seventeenth century England was forced to come to terms with events such as the Civil War and the regicide of King Charles I, in the midst of contending with the cultural changes brought upon by print culture, the effects of which appeared throughout all aspects of English society. These changes helped form a relationship between print and oral culture, one of negotiation among the producers and regulators of work and the society consuming the works. The discussion of this negotiation has led to varying conclusions concerning the true impact of printed materials on English society and culture, all of which tend to see the relationship in one of two ways: print's undeniable and unprecedented influence on culture, or its function as supplement to oral and visual communication. The latter conclusion helped form the foundation of this study, which aims to further understand the negotiation between print and English society. The close analysis of recurring themes of the supernatural, specifically prophecy, witchcraft, regicide, and the natural world, will show unmistakable similarities between popular entertainment and written works. Through the examination of these themes, this thesis will illustrate the extent to which common imagery and wording appeared in newsbooks and what this says about oral communication and culture in early modern England.<br>ID: 031001459; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Adviser: Peter Larson.; Title from PDF title page (viewed July 8, 2013).; Thesis (M.A.)--University of Central Florida, 2012.; Includes bibliographical references (p. 95- 104).<br>M.A.<br>Masters<br>History<br>Arts and Humanities<br>History

Full textAbstract:
The outbreak and continued progress of the Irish rebellion of 1641 played a significant role in the birth and development of domestic newsbooks in England between 1641--49. This thesis examines the manner in which these periodicals reported the insurrection to their readers. As relations between king and parliament deteriorated during the winter of 1641--42, the attention awarded to this uprising by these publications helped to ensure that Ireland became a popular concern. Weekly chronicles of Irish affairs continued unabated after the onset of civil war in England. Amid fears that Ireland could be utilized by Charles I in his struggle with Westminster, pro-parliamentary, and subsequently pro-royalist editors employed the rebellion as part of a propaganda war that accompanied armed conflict in all three Stuart kingdoms. Accordingly, this study suggests that a principle stratagem of the newsbooks was not necessarily to communicate news of Irish matters, but more often than not, their motivation lay in manipulating accounts relating to the rebellion in order to wage political combat in England.

Full textAbstract:
In this thesis, competitive and cooperative newsboy problems for two substitutable products are analyzed by using game theoretic concepts. The demands of the products are assumed to be dependent and normally distributed. Competition is handled for Nash and Stackelberg games. Nash and Stackelberg games are compared in terms of the order quantities and the expected profits. Cooperative newsboy problem is analyzed for the products having equal costs and revenues. The effect of demand correlation on the order quantities and the expected profits in all of the games is investigated through numerical experiments. Optimal solutions of the Nash, Stackelberg and the cooperative games are examined analytically when the demand correlation is 1.

L'objectif de cette recherche est de développer des modèles aussi bien conceptuels, analytiques et managériaux en analysant un maillon de la supply chain, à savoir la relation entre un distributeur et deux fournisseurs opérant dans un environnement incertain. Dans la première partie de la thèse, nous considérons un seul produit, plutôt haut de gamme et/ou périssable, et nous faisons l’analyse sur un horizon d’une période. Dans ce cas précis, les caractéristiques unitaires du produit sont toutes non linéaires, à savoir : le prix, le coût de production, le coût de rupture, le coût de reprise. La demande est supposée être une variable aléatoire. Dans la deuxième partie de la thèse, nous nous inspirons des pratiques de firmes internationales qui s’approvisionnent, pour une partie de leur offre, dans des pays à bas coûts. Nous développons plusieurs modèles mais dont la structure de base est similaire, à savoir : deux produits (un haut gamme acheté localement et l’autre bas de gamme acheté dans les pays à bas coûts), un horizon de trois périodes, deux fournisseurs à capacité de production limitée et un distributeur ayant des capacités de stockage limitées. Une panoplie de résultats théoriques, numériques ainsi que des insights sont présentés.Les modèles développés peuvent être utilisés comme des outils d’aide { la prise de décision dans les environnements décrits dans cette thèse<br>The objective of this research is to develop conceptual, analytical, and managerial models and insights by analyzing a portion of the supply chain made up of a retailer dealing with two suppliers in an uncertain environment. In the first part of this thesis, we consider a single high-end (or perishable) product, single period, variable unit price, variable unit production cost, variable unit shortage cost, variable unit salvagevalue, stochastic demand problem. In a second part of the thesis, we consider settings inspired by the case of large international companies sourcing some of their products from low cost countries. This structure is as follows: two products (one sourced locally and the other sourced abroad), a three-period, two-stages, two capacitated suppliers, and a single capacitated retailer. Both analytical and numerical results are provided. Important theoretical results and insights are developed for these types of settings. These models can be used as decision-making aid tools in such environments

Le management de la chaîne logistique concerne un large éventail d’activités. Nombreuses ceux qui ont un caractère incertain apportant souvent des conséquences inattendues. Malgré cela, l’incertitude est fréquemment non considérée dans la gestion de la chaîne logistique traditionnelle. En plus de l’incertitude, l’indisponibilité des ressources augmentera la complexité du problème. En prenons en compte les contraintes d’incertitude et de disponibilité nous étudions le management de la chaîne logistique selon différents aspects. Cette thèse représente une tentative de recherche afin d’aborder ce problème d’une façon systématique et complète et nous espérons que notre travail contribuera aux futurs travaux de recherche et sera utile aux gestionnaires de la chaîne logistique. Nous nous concentrons sur trois sources classiques de l’incertitude ; celle de la demande, celle la fabrication et celle liée à la distribution. Pour chaque source d’incertitude, nous analysons ses causes et ses impacts sur les performances de la chaîne logistique. L’incertitude est spécifiée dans des problèmes classiques concrets et des approches sont proposées pour les résoudre. Nous nous sommes également focalisés sur le problème bi-niveau de vendeur de journaux qui représente une chaîne logistique miniature, concerné par une double incertitude. Les méthodes utilisées offrent une bonne démonstration du traitement des variables incertaines dans les problèmes de décision<br>Supply chain management involves a wide range of activities. Among most of them, uncertainty exists inherently and always brings some consequence not expected. However, uncertainty is not considered much in conventional supply chain management. In the case where availability of resources is not what we expect, complexity of supply chain management increases. Taking constraints of uncertainty and availability into account, we aim to discuss supply chain management from different aspects. This thesis is an attempt of systematic and complete research from this point and we would like to offer some references to researchers and managers in supply chain. We focus on three classic sources of uncertainty: demand, manufacturing and distribution. For each source of uncertainty, we analyze its cause and its impact to the performance of the supply chain. Uncertainty is specified into concrete classic problem and an approach is proposed to solve it. Furthermore, bi-level newsboy problem as a miniature of supply chain, is focused under double uncertain environment. Treating uncertain variables is actually a treatment on operational level. The methods used offer good demonstration in treating uncertain variables in decision problems

碩士<br>國立中正大學<br>企業管理研究所<br>92<br>The single period problem, that also known as the newsboy or newsvendor problem, is to find a product’s order quantity and selling price that maximize the total profits or minimize total operating costs in a single-period probabilistic demand framework. This study focuses on the newsboy problem with multiple price discounts under certain demand functions. The demand functions investigated include: (1) uniform distribution, (2) triangular distribution, and (3) exponential distribution. The objective is to find the optimal order quantity for each particular distribution. The validity of the derived formula is verified by numerical analysis through a set of illustrative examples.

According to the above establishment total cost expected value, solves the extreme value using the differential the method to obtain the optimal order quantity and the smallest total cost expected value. The optimal order quantity correlates with the parameter of the obeyed probability distribution of the optimal order quantity and the demand quantity. That is, if the parameter is unknown, the policy-maker will not be able to decide the optimal order quantity.
The purposes of this study aimed to obtain the optimal order methods through bringing up several historical data with using order quantity and demand quantity and to divide those data into the complete data and the type I censoring data to conduct the feasible methods of reasonable estimate of the optimal order quantity. On the other hand, the researcher conducted simulation analysis to compare the strengths and weaknesses of those methods. The findings of the study will be able to provide retailers for references to choose the estimation methods and the necessary sample size.

There are three advertising effects in this research. First, in the CVC model, advertising increases only the mean demand. Second, in the CCVC model, advertising increases both the mean and the variance of demand in a proportional fashion. Third, in the ICVC model, advertising increases the variance of demand at a faster rate than it increases the mean demand. The research finds the effects of advertising cost, order quantity and total profit through sensitivity analyses of each parameter.

碩士<br>東吳大學<br>企業管理學系<br>98<br>Single-period Problems always have features such as perishable or having a great discount while overdue. The research incorporates the recourse of placing a second order into the distribution free newsboy problem to develop mathematic models. Under the objective of profit maximum, we calculate the optimal order quantity and optimal lower bound of the total profit and derive useful insights for the managers in inventory management.
There are three models in this research. The first model considers the situation of second ordering and totally backordered. The second model considers the situation of second ordering, totally backordered and penalty cost. The third model considers the situation of second ordering, partially backordered and penalty cost.
The research also studies the effects of model parameters on the optimal order quantity and the optimal lower bound of the total profits through sensitivity analyses, the results are summarized as follows. In each model; (1) when the unit cost increases, the optimal order quantity is a horizontal line, and the optimal lower bound of the total profit increases linearly. (2) when the discount rate increases, the optimal order quantity and the optimal lower bound of the total profit decrease concave upwards. (3) when the increase rate of the unit cost in second ordering increases, the optimal order quantity and the optimal lower bound of the total profit increase concave downwards. (4) when the mark up rate of the first selling price increases, the optimal order quantity and the optimal lower bound of the total profit increase concave downwards. (5) when the mark up rate of the second selling price increases, the optimal order quantity and the optimal lower bound of the total profit decrease concave downwards. (6) when the expected demand increases, the optimal order quantity and the optimal lower bound of the total profit increase linearly. (7) when the standard deviation of the demand increases, if m=d, the optimal order quantity is a horizontal line; if m>d, the optimal order quantity increases linearly; if m<d, the optimal order quantity decreases linearly. The optimal lower bound of the total profit decreases linearly.

Full textAbstract:
碩士<br>中原大學<br>工業工程研究所<br>93<br>Due to the international competition brought about by the global economy, companies need to improve the efficiency of their overall operations in order to increase their profit. Effective supply chain management is one of the ways to improve the overall operation of an enterprise. It promotes the co-operation of all the companies in the supply chain so that global optimality will be realized.
In this research, we present a two-echelon supply chain system consisting of one manufacturer and one retailer. The retailer places a single order in a planning horizon similar to the classical newsboy problem. Our study expands the classical newsboy problem to consider revenue sharing and return policy. The optimum order policy is derived for cases when the expect profit models for the manufacturer and the retailer are developed independently or collaboratively.

博士<br>銘傳大學<br>管理研究所<br>93<br>We take the retailer’s point of view in this research and incorporate information flow between a retailer and customers. And we extend the total expected inventory profit of Dekker et al. (2000) by considering the linear, polynomial, and Gauss holding and penalty cost functions. Two models are considered differing in terms of information completeness with the cut-off transaction size and a compound Poisson demand. The first model involves the retailer has incomplete information regarding the state of customers demand, and the second model involves the retailer has full information about the state of customers. Moreover, we adopt and modify the Golden Section Search Technique (Haftka et al., 1990) to determine an optimal order-up-to level S and a cut-off transaction size q systematically. Finally, the numerical examples are given to illustrate the results derived. It is worthwhile to measure the value of information and identify the effect of factors for enterprise decision making regarding whether or not to pay for information that can help increase profits.

Full textAbstract:
碩士<br>聖約翰科技大學<br>自動化及機電整合研究所<br>95<br>A style dress outlet usually purchases products from multiple suppliers with different cost, quality and selling price. It is assumed that some suppliers will sell their goods to the buyer outright, while some other suppliers will offer return policy for items unsold. In the latter case, the supplier buys back from the buyer the unsold items at the end of the selling season.
The purpose of this study is to enable the buyer to develop a supplier selection and replenishment policy subject to limited budget. A minimal service level and uncertain market are assumed as well. This problem is solved by using KKT Conditions, Heuristic Search Method, Lingo Method, Genetic Algorithms (GA) and Particle Swarm Optimization (PSO).

Full textAbstract:
碩士<br>國立屏東科技大學<br>工業管理系所<br>96<br>Newsboy problem, also known as the single-period stochastic demand inventory problem, is to find the order quantity which minimizes the expected cost or maximizes the expected profit. The classical newsboy model assumes that the demand is a random variable with known distribution. Base on this assumption, the expected total cost or profit function can be constructed and the optimal order quantity can be obtained by using differential method. However, in reality failure to meet demand is always associated with a specified known distribution. Thus, the above procedure to find the optimal order quantity does not work for the classical newsboy problem. The aim of this research is to relax the assumption and to extend the analysis of the distribution-free newsboy model. The analysis is based on the collection of historical demand information and use nonparametric bootstrap method to estimate the optimal order quantity. In order to evaluate the performance of bootstrap estimate, the relative errors are computed when the demand obey exponential, normal, Poisson and negative binomial distribution, respectively. The numerical results will afford retailers to decide on the optimal order of the basis for decision-making.

Full textAbstract:
碩士<br>中原大學<br>工業工程研究所<br>93<br>In the current competitive market environment, enterprises have transformed from an independent decision to a collaborate decision strategy. This is because decisions made independently by one player will not result in global optimum. Global optimality will only be realized if the perspectives of all the players are considered.
In this research, we consider a single-period inventory of product with a fixed life cycle and short marketing period. Our study expands the classical newsboy problem to consider defective items and return policy. The optimum order quantity is derived for cases when the expect profit model in the manufacturer and the retailer are developed independent and collaboratively. Related literatures of classical newsboy problem, defective items inventory system, return policy and two-echelon supply chain integrated inventory model are reviewed. Research methodology of the model development is based on inventory theory, probability and statistic theory. The objective of this study is to derive the optimum order quantity that will maximize the total system profit. Finally, numerical examples and sensitivity analysis are carried out to illustrate the application of the model. From the models, numerical examples and sensitively analysis, it is seen that the optimal order quantity derived increases the manufacturer-retailer profit. This is in conformance with the objective of the integrated manufacturer-retailer channel.

Full textAbstract:
碩士<br>國立屏東科技大學<br>工業管理系所<br>97<br>Newsboy problem, also known as the single-period stochastic demand inventory problem, is to find the order quantity which minimizes the expected cost or maximizes the expected profit. The basic assumption of the classical newsboy model is that the stochastic demand follows a specific probability distribution and the parameters are fixed and known. According to this assumption, the expected total cost or profit function can be constructed and then the optimal order quantity can be obtained by using differential method. However, the parameters in the demand distribution are a reflection of the state of the market and they are shifting according as the characteristics of the reality. In this study, we figure the parameter as the random variable and use the Bayesian framework to construct the total cost function. Thus, the Bayesian optimal order quantity of the newsboy problem can be obtained and we make a comparison with the classical result.

Full textAbstract:
碩士<br>中原大學<br>工業工程研究所<br>94<br>There is an increasing environmental consciousness in recent years. Governments begin to have law on environmental protection. Enterprises must include environmental protection in their innovation and production development. Resource recovery and regeneration to reduce the relevant materials cost effectively is a very important approach to raise enterprise's competitiveness. In addition, enterprises should integrate upstream with downstream to promote the enterprises competitiveness and benefit supply chain members in a win-win situation.
In this research, we consider a single-period of product with a fixed life cycle and short selling period. Our study extends classical newsboy problem with reusable items considering imperfect items and quantity discount. The optimum order quantity is derived for cases with or without collaboration. The model development is based on inventory theory, probability and statistic theory, and use mathematics software to derive the optimal solution which maximizes the system total profit. Numerical examples and sensitivity analysis are carried out to analyze the influence of the inventory system. From numerical examples, it is shown that profit with collaboration is higher than profit without collaboration. Obviously, collaboration is an approach to achieve the objective of the integrated manufacturer-retailer channel.

Full textAbstract:
博士<br>國立交通大學<br>工業工程與管理學系<br>100<br>In this dissertation, we develop a new index “Achievable Capacity Index, I A ”, which can accurately and simply measure the rofitability of newsboy-type product with normally distributed demand. Note that the profitability defines as the probability of achieving the target profit under optimal ordering condition. An unbiased and effective estimator of I A is derived to estimate actual I A as the parameters of distribution are unknown. By using the proposed index, this dissertation also investigate two common problems in the inventory systems, product evaluation problem and product selection problem.
First, we consider the single old stock product. If the new product is introduced, one ought to judge whether the old product is unworthy of being ordered or is curtailed due to the spatial constraint in the warehouse. Therefore, we investigate the product evaluation which examines whether the profitability meets a designated requirement. We utilize the statistical hypothesis testing methodology to tackle this problem. The critical value of the test is calculated to determine the evaluation results. The sample size required for the designated power and confidence level is also investigated. An application example for a fresh food product is provided to illustrate the practicality of the proposed approach.
Practically, the market information regarding demand is sometime obtained from multiple samples rather than single sample. Therefore, we estimate and test I A based on multiple samples. A hypothesis testing for tackling the product evaluation problem based on multiple
samples is presented. Critical values of the test are calculated to determine the evaluation results. A real case on the sales of donuts is presented to illustrate the applicability of our approach.
If the multiple old products are considered to compare each other, we study the product selection problem which deals with comparing two old products and selecting the one that has a significantly lower rofitability. Also, the statistical hypothesis testing methodology is
performed to tackle this selection problem. Critical value of the test is calculated to determine the selection decision. Sample size required for a designated power and confidence level is also investigated. An application example on comparing English-teaching magazines is presented to illustrate the practicality of our approach.

碩士<br>中原大學<br>工業與系統工程研究所<br>101<br>Due to products diversification and demand uncertainty, it is difficult for the manufacturers to predict supply; retailers may suffer from excess inventory or insufficient inventory as well. Therefore inventory management is a very important to ensure a win-win solution.
In this study, we have extended the classical newsboy problem with imperfect items, quantity discount and two warehouses. The objective of this study is to find the optimal order quantity in order to obtain optimize the total profit. The inventory model is solved using Maple 13 and Excel 2007. Numerical example and sensitivity analysis are given to validate the model and to illustrate the effect of parameters value on the inventory cost. Managerial insights are provided based on the numerical example and can be adopted by enterprises in the supply chain.

Full textAbstract:
碩士<br>中原大學<br>工業與系統工程研究所<br>105<br>In recent years, supply chain management has become a long-term business activity. Manufacturer and retailer as the business actors have common financial objective to achieve the profit. The high fluctuation of the total cost can give impact to the profit due to the slight error in the process. Therefore, it becomes challenging to control the error effectively in order to reach the goal.
Regarding to a rapidly changing market under effective time constraints, it is necessary to consider credit payment and profit sharing agreement. Additionally, in order to avoid the delay in customer payments and maximize the overall supply chain profits, retailer has to consider the payment through credit and default risk.
This study considers the demand and the credit transaction period as the random variables to formulate the uniform profit function and total profit function model. Mathematical newsboy theory model and Maple 14 are the problem solving tools used to find the optimal quantity and trade credit period.

碩士<br>東吳大學<br>企業管理學系<br>97<br>Single-period problem always have features such as perishable or having a discount while overdue. The research combines the advertising effects and distribution free newsboy problem .Under the object of profit maximum, calculate the optimal order quantity and optimal advertising cost to provide a managerial insights for inventory controller and marketing persons.
There are three advertising effects in this research. First, in the CVC, advertising increases only the mean demand. Second, in the CCVC, advertising increases both the mean and the variance of demand in a proportional fashion .Third, in the ICVC, advertising increases the variance of demand at a faster rate than it increases the mean demand. We consider two advertising effect functions. First, S shaped advertising effect function. And concave shaped advertising effect function. The research finds the effects of model parameters on advertising cost, order quantity and total profit through sensitivity.
The result of this research are : (1) when the unit cost increases ,the optimal advertising cost, optimal order quantity and the lower bound of total profits increase. (2)when the discount rate increases, except the advertising cost in CVC case is a horizontal line, but decreases in CCVC and ICVC. The optimal order quantity and the lower bound of total profits in three case decrease. (3)when mark price increase, the advertising cost, the optimal order and the lower bound of total profits increase in three cases. In the S shaped function, the advertising cost in three case decreases concave downwards, and in concave shaped function, the advertising cost increases concave upwards. (4)when original demand average increase, in three case , the advertising cost effect in the S shaped and in concave shaped are the same . The optimal order quantity in the S shaped decreases but in concave shaped increases. The lower bound of total profits in two functions increases. (5)when original demand standard deviation increase, the advertising cost in the S shaped and in concave shaped are the same, in CVC it is a horizontal line ,and in CCVC and ICVC it decreases. The lower bound of total profits decreases in all case. There are three situations to discuss the optimal order quantity. First, when m>d the optimal order quantity increases. Second, when m=d the optimal order quantity is a horizontal line. Third, when m<d the optimal order quantity decreases. (6)when the maximum market potential increases, in three case, the advertising cost, the optimal order quantity and the lower bound of total profits increase (7)when the advertising coefficient increase, the advertising cost in S shaped decreases concave downwards, the optimal order quantity and the lower bound of total profits in S shaped are increase concave downwards . The advertising cost in concave shaped are increase concave upwards, the optimal order quantity and the profit in ICVC case increases concave downwards, and in CVC and CCVC increase concave upwards. (8)when the decay constant increases, the advertising cost increases in S shaped , but it decreases concave upward in concave shaped function.

碩士<br>國立屏東科技大學<br>工業管理系所<br>100<br>The main propose of this article is to establish optimal ordering strategy for single period multiple perishable products under stochastic demand. Because the customer arrival time is Uncertainty, so we regard the product’s sales quantity as a random variable and then extend traditional newsboy problem. For practical applications, we divided sales period into weekday and holiday two conditions to explore, and construct multi-product newsboy problem model with space and budget constraints. However, an EM algorithm is provided in this paper that can maximize the total expected profit under space and budget constraints. Then, sensitive analysis is also taken to find out the influence of each parameter for total expected profit and ordering quantity. Then a numerical example is taken to illustrate the model and provide some insights. Finally six conclusions are drawn for practical applications and future studies.

Full textAbstract:
碩士<br>國立成功大學<br>工業與資訊管理學系碩士在職專班<br>104<br>In recent years, the light-emitting diode (LED) industry has been in strong competition around the world. Due to the importance of magnifying the presence of the Chinese LED industry around the world, the Chinese government invested large amounts of resources into the industry. However, domestic businesses can only maximize profit by reducing costs of manufacturing LEDs. During the manufacturing of LEDs, sapphires, a precious and expensive raw material, is used in the epitaxial process. As LED manufacturing methods improve, the estimated mean life cycle of the product will decrease accordingly. However, if the product isn’t sold within the estimated mean life cycle, the product is discarded which is then regarded as an over-stocking cost. On the contrary, if the quantity isn’t met, is then regarded as an under-stocking cost. Thus, our goal is to determine the optimal order quantity of sapphire substrates for LED manufacturing. Many research have already made use of the newsboy model to discuss under-stocking and over-stocking cost problems. However, in our research, we included market interference in our demand distribution analysis, which is not found in other similar studies. Without market interferences, it is much more difficult for predictive data to match the actual data. Because we wanted our predictions to better conform to the actual conditions, we set the demand history as a normal distribution, and three different interferences: normal, uniform, and exponential distributions. In addition, we also conduct sensitivity analysis on the mathematical models.

碩士<br>國立成功大學<br>工業與資訊管理學系碩博士班<br>94<br>The prevalence of the Internet and the prosperity of the Logistics accelerate the coming of the virtual route, causing consumer’s consumption attitude to change. Consumer changes the usual attitude and have great interested in Internet Shopping, TV Home Shopping, and Catalogue Shopping. This research focuses on the product which has the certain selling period in Internet Shopping, TV Home Shopping, and Catalogue Shopping. Because consumer can’t see and touch the product before purchasing, a certain ratio of consumer will choose to return them to retailer in certain time. It is an important question for retailer to decide the optimal ordering quantity.
This research focuses on the newsboy model that consider the selling product which not satisfy the consumer’s demand or the selling product is defect, consumer has right to return the product to the retailer and retailer will pay back its partial or full price. Retailer will inspect and test the returning product, if the returning product does not damage in selling period, retailer will sell it again. But the product which is not sold out in selling period, it has a certain salvage value. Retailer has to decide the ordering quantity to its supplier before the selling period. If the product is sold out in selling period, retailer has an emergency supply option. By constructing and analyzing the model, we can find the ordering quantity of the traditional newsboy model is not suit our model, when the returning rate is more, the ordering quantity of the traditional newsboy model is far from the optimal ordering quantity, and each model has its own optimal ordering quantity in different situation.

Full textAbstract:
碩士<br>國立屏東科技大學<br>工業管理系<br>93<br>Studies concerned with the traditional newsboy models are traditionally focused on one-stage condition to develop optimal ordering quantity formulation to maximize the total expected profit. The price is given and the ordering quantity looks as a decision variable in the previously proposed models. However, in some situations, one-stage before expiry date are unreality. This study targets at problems for perishable commodity accordance with its fresh degrees separate the market into three-stage of price. Unlike previous work, prices are set as decision variables in fitting the analysis of price-quantity relationship economically. To enhance the model more applicable, the purchasing quantity discounts are also considered. The purpose of this study is to develop an optimal ordering quantity model concerning with optimal pricing policies for three-stage market of perishable commodity while considering the purchasing quantity discounts under the nonlinear demand pattern. Sensitivity analysis for the key parameters are conducted on total expected profits. A numerical example designed for different scenarios is finally given to validate the feasibility of the proposed model.
