This paper employs a real options approach to analyze optimal investment decisions. When investment projects have the characteristics of irreversibility, uncertainty and the option to wait or exit, the traditional net present value (NPV) method would underestimate the value of investment, since it neglects the values of timing and operational flexibility. The distinctive feature of this paper is that the effects of product life cycle (PLC) as well as market power are incorporated into the model. In addition, and different to the approach in Liao et al. [Optimal investment decision and product life cycle: A real options approach, Sun Yat-Sen Management Review 11(3) (2003) 1–36], we introduce the concept of technological innovation into the model. It is shown that the optimal waiting time for the investment is longer than both those in the American call options model of McDonald and Siegel [The value of waiting to invest, Quarterly Journal of Economics 101(4) (1986) 707–727], which does not incorporate dividend yield, and Liao et al. [Optimal investment decision and product life cycle: A real options approach, Sun Yat-Sen Management Review 11(3) (2003) 1–36], but is shorter than that in Dixit and Pindyck's [Investment under Uncertainty (Princeton University Press, Princeton, NJ, 1994)] model, which incorporates dividend yield. Finally, a comparative static is used to analyze the determinants of optimal investment decisions. Our results indicate that the investment-ratio threshold will be higher, and thus the optimal entry time for an investment will be delayed, when (1) the PLC is longer, (2) the uncertainty is greater, (3) the discounting rate is higher, (4) market power is larger, (5) jump size intensity is stronger and (6) the payoff out ratio (R&D/revenue) is larger.

The main built environment lifecycle object is building. It consists of 60 different materials and more than 200 different products, with different life cycles and operating processes. The first section of this article contains the built environment life-cycle aproach. The second section contains the built environment life cycle models analysis, sustainable built environment lifecycle conceptual model is composed. The third section gives an overview of the built environment life cycle system created by analyzing the nature of the investment decisions made in economic and environmental terms. The article ends with the conclusions. Pagrindinis užstatytos aplinkos gyvavimo ciklo objektas – pastatas. Jį sudaro apie 60 skirtingų medžiagų ir daugiau nei 200 atskirų produktų, turinčių skirtingus gyvavimo ciklus ir naudojimo procesus. Pirmame skyriuje pateikiama užstatytos aplinkos gyvavimo ciklo samprata. Antrame skyriuje – užstatytos aplinkos gyvavimo ciklo modelių analizė, sudarytas darnios užstatytos aplinkos gyvavimo ciklo koncepcinis modelis. Trečiame skyriuje apžvelgiamos sukurtos užstatytos aplinkos gyvavimo ciklo sistemos, analizuojančios priimamų sprendimų investicijų pobūdį ekonominiu ir aplinkosauginiu aspektu. Straipsnio pabaigoje pateikiamos išvados.
