Productivity and Cost Analysis of Forest Harvesting Operation in Matang Mangrove Forest, Perak, Malaysia

Matang Mangrove Forest is under systematic management since 1902 and still considered as the best managed mangrove forest in the world. This research was conducted to measure the time and productivity of forest harvesting operation and also to analyze the cost and revenue of mangrove forest harvesting operation at Matang mangrove forest. This project had been carried out in cooperation with Seri Sepetang Enterprise, one of the harvesting licenses in Kuala Sepetang, Perak. Data collections were taken in every station starting from standing tree until to the Kiln-Drying jetty. The data then calculated by using the formulas of productivity and cost analysis. As the result, the productivity for felling, bucking and debarking, the manual skidding using wheel-barrow and the water transportation are 1.84 tan/hour, 3.82 tan/hour and 4.64 tan/hour respectively. The cost for each operation of 9 tan log volume for felling, bucking and debarking, the manual skidding using wheel-barrow and the water transportation are RM 56.88, RM 10.80 and RM 36.72 respectively. As the revenue, the company paid RM 260 per 9 tan of log for the in-forest operation (felling, manual skidding and loading to the ship) and pay RM 80 per 9 tan for the water transportation, and they gained the net profit of RM 192.32 and RM 43.28 respectively. The average of forest harvesting operation is twice operation in a day (equal with 2 x 9-ton volume of log production a day), so they will gain a double profit. In conclusion, the forest harvesting operation is sustainably managed for supplying the raw material of charcoal industries in Matang mangrove forest. Since, they work manually and spend much energy in this forest harvesting operation, so for further study it recommends to conduct the ergonomics evaluation during forest harvesting operation at Matang Mangrove Forest

Cost Analysis of Multimodal Freight Transportation: A Case of Iskenderun

In this study from Iskenderun to the other Turkey's 80 cities to unimodal and multimodal freight transportation scenarios are being developed. Filter material which is widely used in İskenderun is chosen for the freight. Highway, maritime and railway transport types are used in route scenarios. The costs of the route scenarios are calculated. Cost calculations are based on 5, 10 and 14 freight tonnage. For the value of the 5 ton freight is 40 000 TL, for the value of the 10 ton freight is 145 000 TL and for the value of the 14 ton freight is 250 000 TL. After the cost analysis is done, the most appropriate route for each province is selected and entered into the geographic information system (GIS). Thus, for freight from Iskenderun, the cheapest mode of transportation can be chosen. It is seen that railway and multimodal transport is widespread in general when the cheapest routes are examined. Thus, along with the shift of freight transport to rail and multimodal transport, traffic density on the highway can be reduced

Radar altimetry systems cost analysis

This report discusses the application and cost of two types of altimeter systems (spaceborne (satellite and shuttle) and airborne) to twelve user requirements. The overall design of the systems defined to meet these requirements is predicated on an unconstrained altimetry technology; that is, any level of altimeter or supporting equipment performance is possible

Energy Usage and Benefit-Cost Analysis of Castor Production in Haryana

The study used farm level data collected from rain-fed and irrigated castor seed cultivators from three purposively selected districts namely Rewari, Sirsa and Hisar of Haryana on the basis of highest acreage under castor crop. From each selected district, two villages were selected purposively having large number of castor cultivators. Sixty castor cultivators were interacted to extract relevant information related to various energy utilized in castor seed production using survey method. The aim of this research is to determine the energy input and output involved in castor production in the Haryana. The average energy consumption of the farms investigated in this study is 11064.18 MJha-1 of the total energy, 23.67 per cent is direct and 56.56 per centwas indirect. Renewable energy accounts for 3.49% and energy usage efficiency is found to be 5.92. The total energy input into the production of one kilogram of average castor was estimated to be 8.55 MJ. The dominant contribution to input is energy in the form of nitrogen fertiliser (32.86%), followed by water for diesel- oil (20.61%) and irrigation (19.77%). The cost of castor production per hectare is found to be ` 97412ha-1 in the region, with 52.70% of this beingfixed costs. It can be concluded that intensive castor farms are being operated in the area since the fixed cost was quite high. As a result of benefit-cost ratio (1.48) analysis, castor production was found to be economically efficient

Realtime market microstructure analysis: online Transaction Cost Analysis

Motivated by the practical challenge in monitoring the performance of a large number of algorithmic trading orders, this paper provides a methodology that leads to automatic discovery of the causes that lie behind a poor trading performance. It also gives theoretical foundations to a generic framework for real-time trading analysis. Academic literature provides different ways to formalize these algorithms and show how optimal they can be from a mean-variance, a stochastic control, an impulse control or a statistical learning viewpoint. This paper is agnostic about the way the algorithm has been built and provides a theoretical formalism to identify in real-time the market conditions that influenced its efficiency or inefficiency. For a given set of characteristics describing the market context, selected by a practitioner, we first show how a set of additional derived explanatory factors, called anomaly detectors, can be created for each market order. We then will present an online methodology to quantify how this extended set of factors, at any given time, predicts which of the orders are underperforming while calculating the predictive power of this explanatory factor set. Armed with this information, which we call influence analysis, we intend to empower the order monitoring user to take appropriate action on any affected orders by re-calibrating the trading algorithms working the order through new parameters, pausing their execution or taking over more direct trading control. Also we intend that use of this method in the post trade analysis of algorithms can be taken advantage of to automatically adjust their trading action.Comment: 33 pages, 12 figure

GENERALIZED COST-ANALYSIS OF SCREENING PROGRAMS

Nowadays, there is a growing interest about including indirect costs of health care programs in economic evaluations. In this paper, we provide a generalized cost-analysis of screening programs and propose a technique to measure production gains associated with these programs. We apply this technique to show evidence in favor of implementing a newborn screening program to detect congenital hearing impairment.Production gains, screening programs, cost analysis, potential social earnings.

The Relationship between Cost Analysis and Program Management

Cost analysis if often viewed as applying basic principles and cost methodologies to determine total system cost. These finished estimates then flow into a decision making process and the cost estimator leaves the stage. Reality shows that the cost estimator is actually one of the main contributors to the decision making process. Our introduction to this special issue explores the areas where cost estimating plays a major role in program management in areas beyond the normal program estimate. We have included articles that show the key role estimators can play in source selection strategies and evaluation; cost of delay analysis for management decisions, earned value management methods to predict program costs; decision criteria to rank competing projects that complement traditional cost-based methods; and a new methodology for determining research and development budget profiles
