furrow irrigation is the most common type of surface irrigation. determine the advance and recession time in the field is required the accurate measurement and this can be costly and time consuming. winsrfr model is used for simulation furrow irrigation by zero inertia and kinematic wave engines. using this model, advance time, reaction time, infiltration depth, runoff depth and application eff...

We discuss a multi-objective/goal programming model for the allocation of inventory of graphical advertisements. The model considers two types of campaigns: guaranteed delivery (GD), which are sold months in advance, and non-guaranteed delivery (NGD), which are sold using real-time auctions. We investigate various advertiser and publisher objectives such as (a) revenue from the sale of impressi...

This study aims to determine the construct validity and reliability of PedsQL 4.0 among a sample of Malaysian adolescents and parents. METHODS A cross-sectional study was carried out a...

This paper reports an experiment conducted to assess the effects of alterations in production conditions and product durability on market power in Bertrand-Edgeworth duopolies. Experiment results indicate that advance production increases market power in the sense that mean transaction prices increase relative to static Nash equilibrium predictions for a baseline market. In a similar way, a sim...

This paper presents an integrated imperfect production inventory model under two layer supply chain management. To ensure the orders, manufacturer convinces retailer to pay a percentage of purchasing cost prior replenish products and offers facilities such as (i) delay in payment on remaining part (ii) free transportation basis advance amount. Time dependent development is incurred maintain rel...

This paper considers inventory models with advance demand information and flexible delivery. Customers place their orders in advance, and delivery is flexible in the sense that early shipment is allowed. Specifically, an order placed at time t by a customer with demand leadtime T should be fulfilled by period t+T ; failure to fulfill it within the time window [t, t+T ] is penalized. We consider...

This paper studies the inventory system of a retailer who orders his products from two supply sources, a local one that is responsive and reliable, but expensive, and a global one that is low-cost but less reliable. The deliveries from the global source only partially satisfy the quality requirements.Wemodel this situationwith a dual-sourcing inventory model with positive lead times and random ...
