Study On The Ship Investment Of Shipping Enterprise

International shipping business is a service industry with huge capital and high investment risk. One of the important contents of the business of shipping enterprises is ship investment which is quite strategic as it concerns the general operation of shipping enterprises and the changes of their fleet structure and the transportation of their capability. Under current situation of the diversification of the shipping industry especially, it has become the urgent fairs that shipping enterprises work over how to maximum avoid the investment risk and then set down satisfying ship investment plan rightly.With the development of the investment risk, the evaluation method of ship investment faces challenge under the new situation. The traditional evaluation methods such as CF etc., which make the ship investment, are in terms of increasing the income mainly. But new methods consider such many kinds of risk factors as the ship market cycle, investment repayment, management environment and the constant variation of shipping market etc. It is impossible for the traditional mathematical optimum models to solve such a problem with so many uncertain risk factors. However often specialists obtain a satisfying ship investment plan by judging risk factors with experiences. But planning by experiences has no theory background and may be affected by some accidental factors such as the knowledge, the emotion and even the experience of different specialists.This paper uses developed investment risk evaluation in foreign countries and regions for reference after analyzing investment risk characteristics of shipping enterprises. And combine the society, the situations of economy, the culture development and stage that the development of risk evaluation in China, adopt the Varied Weightiness and the Relative Deviation analytic approach of the level to set up stronger effective ship investment risk evaluation index, risk evaluation mathematics model on the basis of setting an example of ship investment in CSTRAMP. This approach not only maintains both merits of the mathematical optimum model and the specialists planning but also avoids the shortcomings of the two traditional approaches. The Varied Weightiness can systematically solve a planning problem concerning both quantitative and qualitative risk factors, and it can even deal with the problem with uncertain risk factors and indicate the attitudes and biases of shipping enterprises. And it can enhance the credibility of Varied Weightiness in the application through the use of Relative Deviation. The risk evaluation that this paper set up can start an undertaking go on project risk evaluation and offer meaningful reference for investment, and offer basis on both sides of the negotiation. Consequently, the risk evaluation mentioned in this paper starts an undertaking to the pioneering enterprises, development of shipping enterprises and institutions of risk investment in our country look for domestic and international opportunity to invest that have realistic directive significance meanwhile.
