Hook were collected from Mussoorie (2205 m), Bhatwari (1218 m) and Bhaldana (850 m) from Garhwal Himalayas and their essential oils were isolated and subjected to GC and GC/MS analysis. The oil yield was lowest (0.2%) in the plants collected from the relatively higher altitude of Mussoorie; it was rich in borneol (21.2%) followed by linalyl acetate (7.4%) and α-humulene (6.7%). The oils from plants collected from the lower altitudes of Bhatwari and Bhaldana yielded higher percentage of oils (0.8–0.85%) which were dominated by β-caryophyllene (16.3%, 18.4%) followed by α-thujone (12.0%) in the former and eugenol (16.2%) in the later.

Effect of declining selling price / S. Banerjee in Journal of the operational research society (JORS), Vol. 61 N° 4 (Avril 2010) 

Public ISBD [article]  in Journal of the operational research society (JORS) > Vol. 61 N° 4 (Avril 2010) . - pp. 696–704 Titre : Effect of declining selling price : profit analysis for a single period inventory model with stochastic demand and lead time Type de document : texte imprimé Auteurs : S. Banerjee, Auteur ; N. S. Meitei, Auteur Année de publication : 2010 Article en page(s) : pp. 696–704 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Inventory  Random  lead  time  Declining  selling  price  Lost  sales  shortage Index. décimale : 001.424 Résumé : In this paper, considering the empirical trend for sales and price of fashion apparels as prototype, optimal ordering policy for a single period stochastic inventory model is investigated. The impact of the presence of random lead time and declining selling price on the profitability of the retailer is explored. Existence of unique optimal solutions for net profit functions is proved. Numerical examples are presented to illustrate the method of identifying profitable levels of inventory holding and penalty costs. Percentage profit per unit investment in inventory is obtained in order to assist managers in taking business decisions, specifically to the extent of whether or not to take up a particular business under known constraints. It is demonstrated that the optimal inventory policy in the absence of price decline and lead time differs considerably from that when lead time and price decline are simultaneously considered.

Solution of single and multi-objective fixed reorder quantity system by general fuzzy programming technique / S. Banerjee in International journal of management science and engineering management, Vol. 5 N° 5 (Octobre 2010) 

Public ISBD [article]  in International journal of management science and engineering management > Vol. 5 N° 5 (Octobre 2010) . - pp.323-333 Titre : Solution of single and multi-objective fixed reorder quantity system by general fuzzy programming technique Type de document : texte imprimé Auteurs : S. Banerjee, Auteur ; T. K. Roy, Auteur Année de publication : 2011 Article en page(s) : pp.323-333 Note générale : Management Langues : Anglais (eng) Mots-clés : General  fuzzy  non-linear  programming  Fuzzy  optimization  Fuzzy  non-linear  programming  Stochastic  inventory  model  Membership  function. Résumé : This paper considers a multi item single period inventory problem with floor space constraint where the demand of the items follows probability distributions. Two different stochastic models are discussed where the demand follows Uniform distribution and Exponential distribution respectively. Firstly the fixed reorder quantity system with backorder and secondly fixed reorder quantity system with lost sales are discussed. Then consideration is adopted as a multi objective stochastic inventory model where average annual cost of the first item as well as the same of the second item are minimized simultaneously and is also formulated in fuzzy environment introducing fuzziness in the objectives. In this paper the concept of General Fuzzy Non-linear Programming Technique is applied to solve a multi objective single period stochastic inventory problem with floor space constraint. The solution is illustrated by numerical example and the results of different models are compared.
